Is it a good idea to buy some crypto for long time investment plan from exchanges such as binance as keep it there, any alternatives ? Because i have heard bad things about some famous exchanges such coinbase.
Buy cryptocurrency in different exchanges such as Binance, and better to stored it in trezor or nano ledger or in any hardware wallet that you want, I believe that it is more secure to save and hold it in that kind of wallet, but be sure that your devices has a good security as well, I don't store my coins in an exchange not because I don't trust them , it is just for myself for assurance since no website is 100% from attacks.
