Token Sale: How to Choose Genuine Project

Token sale is a crypto related phenomenon became trendy last few years. Token sale is often interpreted as ICO. Actually, there is no difference between the terms — both are used quite liberally in the crypto community. Token sale is the key means of raising capital for startups to help crypto enthusiasts launch their project.

It has inherited principles of crowdfunding:

-You have something to offer;

-You announce your product, its features and prospects to gain prominence;

-Within specified time-frames, you raise money from your project’s followers who want to back it.

-You launch your project by their means and provide them with exclusive benefits. In the token sale context, you distribute the underlying token of your project among the backers before listing it on trading platforms.

Token sale is a powerful tool for creating cutting-edge projects based on blockchain and take them to the mainstream. Unfortunately, some shady projects use it to trick trustful users into backing them. A super-revolutionary, prospering, world-changing project may turn out to be a unicorn yet another crypto scam. So how not to fall prey to fishy token sales? And how to tell whether a project really deserves your attention and trust?

What you should know


The project team is its driven force. The more professionals are involved, the better the results. Saw someone well-known in crypto community participating in the project? Great! Saw a celebrity? Well, check the team twice. If Ryan Gosling is about to run an ICO, you, probably, should get somewhat suspicious.

Key features

What does the team offer? Do they build a competitive and transparent business model? Check what they did before and what projects they worked at in the past. Not impressed? It would be better to look for something more persuasive.


As you may know, the certain percentage of tokens to be released is held by the core founders of the project (around 25% of all issued tokens). If one project has too many founders and token holders, you should take a closer look at their activities. Pay also attention to hard and soft caps. A hard cap is the absolute upper limit of the amount the team aims to raise during the crowdsale, whereas a soft cap stands for a lower barrier. The difference between those shouldn’t be huge. If the funds raised exceed the high cap or, on the contrary, don’t reach to the soft cap limit, this is a red flag.

Social media and community

Check the presence of your project on social media and Reddit, in particular. What do people say and how does the staff react? This moment is crucial since you can detect potential scammers, regarding their reaction, if any.

Reviews and analytics

Google the project you are about to invest in. Is there any information on that? If it is, what do experts say about that? The more information you get, the better. Do not invest in a project that doesn’t contain anything valuable.

News and updates

What lesson can we learn out of these fancy stories about ICO affairs? Always check the news and press releases of the project on large and reputable sources dedicated to crypto. Stay up-to-date with every single step of the team and check analytics. Chances are, you will not be caught in a trap.


Whitepaper is the essential information about the project. Reading this will give you a full understanding of the project’s ideology and philosophy. The project should aim to resolve real matters and provide real solutions. Don’t believe in miracles. At least, when it comes to blockchain technologies.

One in a million?

Google, Facebook and other large platforms take measures towards ICO advertising. There are reasonable causes to do so since more than 80% of the overall number of token sales are claimed as scams. In fact, things are not so bad as they may seem, if only because Changelly has listed a range of prominent tokens issued via ICO: Stratis, Patientory, Storj, Salt, Stox, Viberate, and many, many more! So if you want to back a token sale, just do it deliberately with careful comparing all pros and cons.

Where to store crypto?

Even though cryptocurrency and blockchain now are well known to public, there are still millions of questions about where to store crypto.

So, how can you actually possess a bitcoin or any other digital money? Let’s focus on one of the most important cryptocurrency part — a wallet. This one is tricky, it may seem quite understandable from the first glance — a wallet where you store your digital coins! — But it is not as simple as it looks.

What’s the trick?

The biggest difference from the traditional electronic wallet is that cryptocurrency wallet does not store your money in one place, it provides you with the access to your public keys and private keys and transaction records on different blockchains. Everything related to crypto is happening on the blockchain: for example, when somebody is sending you a cryptocurrency, the person simply signs off the ownership to your wallet address. A new block appears in blockchain, gets confirmations, and your wallet shows your new balance.

Public & Private keys — What is it?

A transaction is a process which includes encryption using a pair of keys. Simply put: a public key is used for encryption, a private key — for decryption. All wallets have private keys stored in their files. Keys has strong mathematical relations with Bitcoin addresses and are generated by wallets. Anyone who has private key has control over funds. Some wallets can own your private keys but they can’t have access to use them. Using wallet software you get access to your private and public keys so that you can monitor your balance, send money, and make other operations.

Hierarchical Deterministic (HD) Wallet Keys

Wallet software can use the specific seed for generating private keys from a single value. Wallets using this type of private keys generating are called a hierarchical deterministic wallet, or HD wallet. The seed value should not be confused with the private keys used directly to sign Bitcoin transactions. Don’t confuse seed value with the private keys, seed values are not used to sign Bitcoin transactions.

HD wallets need to be backed up only once, usually using a mnemonic phase of 12 words. Using this phrase you will be able to restore same private keys. Other wallets generate new private keys for each new address. In case such wallet file is damaged — you won’t be able to restore anything so that your funds will be lost.

All right, but aren’t all these wallets same?

Depending on your preferences, you can choose the way to store your digital money.

There are three basic types of cryptocurrency wallets:

1. Software — it can be a site or an application for your PC or smartphone.

2. Hardware — devices to store your currency, can look like USB-drives. Most of those you got to purchase before use.

3. Paper wallet — a paper document including all the information for creating any number of private keys. Also, paper wallet is usually mentioned as an offline key storage as a physical document.

Do I need a wallet for each cryptocurrency?

Some wallets support several cryptocurrencies, some are made exclusively for one currency.

Let’s look at the most popular Ethereum, Bitcoin mono wallets.

Bitcoin Mono-Wallets

Ethereum Mono-Wallets

Now here’s a short list of multicurrency wallets where you can keep different coins.


Here are some tips to make your digital funds safer:
1. Keep the majority of your funds offline, use smaller amounts in your daily use. Backup your wallets!
2. Use as more authentication steps as possible. You may also use multi-signature wallets which require permission from another person before transaction initiating (e.g. your spouse).
3. Update your wallet and device software. New software versions make sure that you have up to date security.
4. Keep your private keys safe.

It doesn’t matter for Changelly which wallet you use to make an exchange, we only care if you feel safe with the one (or more) you choose!

How to avoid transaction fail due to low amount?

So, it happened that your transaction is unfortunately failed, and it takes time to contact our support team and find out what happened. But there are common reasons why transactions fail that can easily be avoided.

One of these reasons is a low amount of coins that we have received from you.

When you set up your transaction, we warn you about the minimum amount that you can exchange. This amount includes the output transaction fee on our end but doesn’t include the transaction fee on your end. If the amount you send turns out to be less than minimum requirements due to a network fee on your end — transaction fails.


Even if you set up a transaction with the appropriate amount, there is still a chance to send less, so you should be very attentive. It happens quite often when changing 0.00199 BTC, for example, you can accidentally send 0.000199 BTC. In this case your transaction is failed and non-refundable.

Network fees

Don’t forget about network fees when sending the payment to Changelly. You must remember about including possible fees in the amount you are going to send to our address, since some wallets show you transaction fee, others don’t, so you got to look for it in the settings. Changelly deducts the network fees at the end of the exchange. If the network fee turns out to be more than the amount exchanged, we won’t be able to send it.

Refund or not?

The low amount can be refunded whenever the transaction is failed before exchanging. In this case, we may refund the low amount, provided it is enough to cover network fees. If the amount is insufficient or exchanged already, the refund is technically impossible.

Changelly strongly insists on checking twice the sum you’re about to exchange.

Don’t panic if you send less, if there is still enough to deal with network fee our support team will get you a refund.

If you have any other questions, don’t hesitate to ask at

Why network fees are floating?

If you are accustomed to the crypto world somehow, you are likely to know about network fees. These are small amounts of coins anyone sends as a reward for miners when doing any kind of transaction in blockchain. The bigger network fee, the higher the priority of your transaction. In some cases, you may encounter unfortunate issues related to large network fees and a smaller output amount, as s result. Eventually, you may wonder how come the output amount turned out to be way smaller than expected. In most cases, the answer is in floating network fees that are always deducted from the amount to send.

What do network fees depend on?

Actually, the network load determines how much you should pay miners for your transaction. Imagine your transaction going up for auction, where your bid is the transaction fee. It if is more than average, chances are, your transaction will be processed faster. The average transaction fee can fluctuate depending on the number of transactions pending. Simply put, if the network is overloaded, the average network fees increase. Likewise, if it comes back to normal or doesn’t have any backlog, the fees become much lower.

What about Bitcoin and Ethereum network fees?

If you remember Bitcoin mass hysteria at the end of 2017, you may know how outrageous the network fees may be. In comparison with that moment, the current Bitcoin network fee of transactions made through Changelly has dramatically decreased — to only 0,00065 BTC.

Same is relevant for Ethereum. Over the last month, the network fee has dropped down from 0.00063 to 0.000315 ETH on average.

High times for exchanging

The market is calm. The network fees are comfortable. The volatility is low. Hence, if you’ve ever wished to buy crypto, this is the very moment to do it without freaking out of every sudden market swing.

With Changelly, you can do it in a few clicks, whether you’re about to exchange one crypto asset to another or buy it with your bank card.
