Guys is it safe to just put the purchased tokens on the exchange? cause i dont have a wallet in my android app. is it possible that it will be stolen? and claimed to be hacked? Am i doing the right way? Please can anyone help me. Thanks in advance.
Yes, it is safe to put it on the exchange, all exchanges have security measures to secure ones investment, However it is more better to have a wallet such as Myetherwallet, Coinbase, etc. to be more secure and keep it safe. Remember just be more responsible with your private keys.
Coinbase is not a wallet and where you can't store tokens yet maybe in future can.But now coinbase only supports four cryptos BTC.ETH,LTC and BCH.
For OP it is not safe to store your crypto in an exchange because you are not controlling the private key so chance of hacking is possible so move it to a wallet which have private key access.
