Decentralized Exchange (DEX) is the future. For now, a lot of people still don't appreciate these decentralized exchanges and they have some reasons for it.
Like why they intend to stay using centralized up until now.
I'm not telling centralized exchanges are really bad, but there are just pros and cons to both centralized/decentralized exchanges. Depends from your goal if decide which one to use.
There is no future for decentralized exchanges. In a few years, most of the cryptocurrency market will be regulated by the SEC and similar regulators. Recently, in a closed group, there was a conversation with a representative of a major exchange from the top 20.
Regulators send them recommendations, but do not force them to comply with these requirements. The requirements of the SEC apply to most countries, and if a crypto exchange refuses to comply with these requirements, then it will be banned in many countries. The same applies to large decentralized exchanges. They will all cooperate with regulators.Of course, there will be ways of decentralized exchange in new projects, but they will be greatly inferior in terms of liquidity and opportunities.
