In crypto currency field, I prefer a centralised than decentralised when it comes to using an exchange so I can get with customer support when something goes bad.
Not sure if you were drunk while writing this or you are here just to spam the forum. Why would you want crypto currencies to be centralized. Decentralization is one of the most important feature for crypto currencies. Cryptos were actually first made so that people can have control over their own coins with no third party involved. If you are fond of centralized currency, then just use fiat and the traditional banking system. Crypto currencies would be pointless to you.
