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.
Yes binance is trusted and good to store coins but it is not suggested or recommended by experts because there is always risk to store your coins at third party exchanges or wallets without the private keys. So what you can do is after buying from exchanges you should transfer the coins to your private wallet in this way you will be in full control of your coins and investments.
