how we can sell and parchase crypto like BTC etc can we deposit directly into our account because in my country BTC and all others crypto is not acceptable
i her that there are lots of 3rd party platform available for that and also online exchange company corporation
You can sell and buy crypto using either centralized exchange (which I don't like except you must) and decentralized exchange. You can check in the forum service board and find many exchange platforms, create an account with anyone that's accessible from your country and you're good to go.
If you choose a centralized exchange in buy your crypto, then make sure to not leave your asset in the Cex after buying
You can create a selfcustody wallett like electrum wallet where you can transfer your assets safely into and be responsible for it . Never leave your funds in a Cex, never.
