first, if you want to buy and sell bitcoin, you can buy and from your friends which have legit seller.
second, you can find market exchanger that would not need to verify but you can still trading. i think its a small market exchanger. its good better than not trading
in polo, i think you can still trading while you don't have to verify your ID, but if you want to reach the limit, you must verify your ID.
thats what i do and my other friends do. at least we can trade while its just small amount without to verify ID.
