Next dot exchange is a cryptographic exchange that deals with digital assets of any kind. Thus exchange is neither centralised nor decentralized but actually combines the positive features of a centralized and a decentralized exchange in order to make a perfect exchange, which is why hybrid exchanges aren't that popular. This exchange was founded in 2017, unlike other common exchanges, like Binance, OKEx, Kucoin etc, Next Exchange was built on its own private blockchain known as Next chain. This blockchain uses proof of stake and proof of work mechanism to operate. With the use of this mechanisms like POS and POW, traders can be able to enjoy reduced trading fee and almost 10,000 transactions per second. I didn't trade here since, the exchange was marked as an Untracked Listing on CoinMarketCap and there wasn't any known trading volume for this exchange.
