I don’t know any hybrid exchange that is currently operating. If someone knows any, I would be grateful for naming them. So, considering building a cryptocurrency exchange, focus on a hybrid one. There are many centralized exchanges, which gained a reputation in the course of time, as they were the pioneers in the crypto market. I think it’s unlikely a newly launched centralized platform would be able to compete with such established giants as Coinbase, Binance, Bitstamp or CEX (

The decentralized exchanges fell short to deliver easy-to-use platform though they are highly secure, unlike centralized exchanges. The users don’t want to bother with the complex site, they need simplicity. This obstacle reduced the demand for decentralized exchanges. Therefore, in the vast majority, they have low trading volumes that additionally make them less attractive for trading. Thus, the niche for hybrid exchanges is open. IMO it would be easier to reach the audience, as you would be the pioneer.
