Liquid exchange is an exchange that was born out of the merger of Quione and Quionez. It was launched in 2018 and it is based in Japan.
This exchange is strict regarding security and this is a big plus for them. Starting with sign up stage, all intending investors and traders are required to provide a lot of valid documents for verification. Also at withdrawal stage, no automatic confirmation of payment. Each withdrawal is processed manually. This is exactly the way Revain confirm withdrawal. Although some unwary investors or traders may count this against them, seeing it as slowness on their part, but security should never be compromised or traded for speed.
Liquid exchange offers many cryprocurrency pair, upward of 70. It also offer crypto/flat Currencies trading. Its daily trading volume is very high except for the pandemic that has recently reduced it and I believe this is a general problem for all exchanges.
In terms of fee, it is noteworthy that their trading fee is slightly above the industry standard. For instance both takers and makers pay 0.30% against the 0.25% industry standard. Also, withdrawal fees is charged currently at 0.0007btc against the industry standard of 0.0006btc.
Conclusively I personally commend the exchange and believe in them. I also know that any investor or trader that put security first will see liquid exchange as their first exchange.
