How to Choose a Cryptocurrency Exchange According to Cryptonit Founder

Konstantin KaratovBitcoin price is swinging near its historic maximums of $15,000. There is much hype on the market, new inexperienced players are coming. What do you need to know about cryptocurrency exchanges not to get burned by investing in bitcoin? Konstantin Karatov, business developer of Finom Blockchain Corp and founder of Cryptonit exchange has prepared a digest of the world’s famous cryptocurrency exchanges, and also explained why some of them go offline for days and even weeks.

Cryptocurrency exchanges involve risks resulting from the key feature of bitcoin or any cryptocurrency as such. Bitcoin is electronic money to bearer. It means that a person holding the private key to the wallet owns the bitcoins in it. While you keep cryptocurrency in your wallet, there is no need to trust anything to a third party. As soon as you transfer cash to the wallet of the exchange, the latter, in fact, becomes its owner. It is the exchange that also becomes responsible for its safety. The only thing you will have to do is trust the service.

Less than 30% exchanges trust their users to have the right to govern the private key – most businesses take complete hold of storing the assets. Thus, when choosing an exchange, it is reasonable to make sure its management is knowledgeable and responsible enough to protect your cash from hackers or technical bugs.

How to Choose the Exchange?

First, make sure the exchange has a so called cold storage that provides holding the main assets of the exchange offline. All major exchanges use cold storage with up to 80% assets there. Cold storage is essential for keeping most assets safely protected in case of an eventual malefactor attack.

Secondly, the person running an exchange should have flawless reputation. Make sure the Exchange has a continuous feedback channel. If the Exchange is anonymous, this is sure to be a red flag. We have seen many examples of exchanges closing down without any refund for their users. Thus, in July 2017 the oldest Russian speaking Exchange BTC-E left the market, stripping its users of $95 mln. Three years ago, Mt.Gox was the major exchange. It lost $450 mln, went bankrupt and left the market.

Thirdly, check the daily trading volume. It is one the key indicators of the exchange activity. The higher it is, the better. The trading volume of major exchanges may be as high as $300-500 mln a day. Before investing, make sure to read carefully the conditions of placing end withdrawing assets, make note of charges and of the payment systems supported.

As for security, most exchanges provide two-factor authentication for their users. This is nothing new. It is the fact of having a government license that is not quite obvious. Only every third major exchange has got it, whereas the number of smaller businesses that care about obtaining one is of a much higher order.

All exchanges support Bitcoin. Ethereum is the second current, followed by Ripple. The most widely used national currencies are USD, EUR, JPY, CNY and KRW.
