And what is the principle of trading precisely on a decentralized exchange? The fact is that at the moment there is not a single truly decentralized exchange on which there is liquidity. I see no problem using centralized. I think in a few years there will be really big and decentralized exchangers.
There are some things that traders concern, there are those who prefer transaction speed and high volume so that they can quickly sell or buy CEX of their choice, but there are also traders who are concerned with security and DEX is often the choice of traders like this.
I'm not often using DEX sometimes use IDEX and WAVESDEX but not the first choice, I only feels safe leaving the assets being traded on DEX.
