The reason of making Bitcoin in the first time is decentralized money and make P2P safely but now we can see many platform start controlling this crypto currency by KYC .
My question is can we make platform that can we verify account by deposit only .
Account have two wallet one of crypto and other with real money he can swap and withdrawal money or crypto anytime
Still not clear with the Ops intention Op said Bitcoin was for the decentralization and P2P anonymous medium of exchange but then Centralized exchanges jumped and started controlling crypto and they did and they are doing by manipulating the market from time to time. So coming up next to it I would like to add up things now OP is asking for a decentralized exchange without KYC.
Answering after explaining the query, Op we already have such types of platforms in the market such as decentralized exchange for trading crypto and even crypto to fiat we can trade with just the mechanism which OP is interested in. So OP if you want to know about these platforms s you can learn by just a few searches even I will give the hints to you.
►Mention on which Chain you are holding assets
►Search with the name of the chain about decentralized exchanges available on that exchange.
►Simply connect your wallet with that platform and enjoy decentralized trading with smart contract-based marketplaces.
