But there are still other P2P platforms from exchanges like Binance, KuCoin, OKX, ByBit, etc., that we can still use as of the moment.
As Some other members already mentioned, Those Centralized exchanges don't offer you Real P2P. P2P means Peer-to-peer. But, Those exchanges act like escrow.
DEX platforms are new. so they have yet to hit the scenarios localbitcoin sellers are hit with due to lack of popularity.. however when DEX seller get popular and start doing too many wire transfers or getting scammed and treated as thieves. they too will end up shutting up shop or going official.
thus DEX wont change things, its just the same saga in repeat. where DEX is just at the beginning and yet to hit the drama
EtherDelta was the first known DEX. It's been a couple of years since DEX's are in the market. So, I won't say all DEX platforms are new. Do you think that someone from the EtherDelta team was Involved in the EtherDelta hack? Right after the hack, They have been forced to suspend their service to due the alleged hack.
