Most crypto traders make use of centralized trading platforms, like Binance, Bitmex, Poloniex, Bittrex etc
The hype around these platforms made it appear to most guys in the cryptospace as the only available option, very small percentage of the crypto traders population have an idea on how decentralized trading platforms works.
Obviously centralized trading platforms are easy to use and all that! , but thats not the best the technology can offer, I believe the future lies in decentralization, with that we can achieve maximum security. Personally i trade on a decentralized platform, because i got tired of the issues surrounding the centralized systems.
What is the name of the decentralized platform you are using? Would be good to share if you do not mind.
I confess that I have tried any decentralized perform since I have only a small amount to trade Bitcoin and Ethereum at Bitstamp. There is always a risk of scam, but in the case of Bitstamp it's been reliable and I love their rates and the liquidity available.
The most serious issue however is the possibility of a big hack like it happened in South Korea. I guess that's why more and more people just like you, are going for decentralized exchanges.
