eIt is a common occurence to see exchanges which started out as a legit exchange just suddenly close off without a prior announcement to its users. As a recent and a new trader in the cryptosphere, I have come across various exchanges and have even used some of them which turned out to be scam exchanges later on. There's no known cause for the sudden disappearance of this particular exchange. In today's review, I'll be writing about Serenity exchange. This is a spot, OTC, derivatives and margin exchange allowing for the exchange of various cryptocurrencies. It was launched in 2019, it claims to use a technique called Liquidity Aggravation which draws liquidity from other exchanges, hence becoming a liquidity based exchange. This exchange has actually been recording a trading volume of $0 for more than 30 days. It doesn't look active, stay away!!!
