I think it's much safer to trade in Decentralized this year than two years ago, people are more educated now, on how to trade n Dex and besides they are not likely to get hacked by hackers, because they are not getting huge amount of tradeable coins than when they are going to do it with prominent centralized exchange.
It is safer to trade on decentralized exchanges, you have your coins in your wallet and you have the private keys that opens that
wallet. In centralized exchanges they have your coins because they have the private keys.
I think in the future people will use decentralized exchanges more. Like you say people will learn about what is safer and they will
go where it is safer! We just need more time and more education about these matter, when people learn about it they will know what
is the best for them.
