Hi,
I want to earn interest on my coins (BTC,ETH,LTC) therefore I prefer to leave these in Exchange for funding purpose, however I have No plan to sell or exchange with other coin in near future.
I always keep my withdrawal blocked by changing password every 5th day.
Is it 100% safe to keep crypto's in exchange like Bitfinex or others with withdrawal locked ?
I suggest is to make a half of altcoins on exchange and the other half should stored on your hard wallet to keep secured your all accounts. If you have on the exchange, supposedly to be have a 2FA Security so that you will keep safe your altcoins. And if you want to hold for a long term just make sure to put them on the compatible wallets rather than to sell it
I would like to make divide into three. Some you keep into exchange wallet, some you keep into software or electronic wallet and other you just cash out. Only problem for exchange is that you do not have any control by you. Even, if by any how exchange got hacked then whatever security you have none will help until or unless exchange can keep safe and protection all of their user accounts. However, without keeping exchange it is impossible to do any kind of trade.
