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 ?
There is nothing 100% secure where sometimes you don't get access to your coins just because of carelessness or negligence...I have here for example on the exchange is two factor authentication, the key from which I kept on my laptop...I went for 2 days to rest in another city, and when I arrived I was flooded by neighbors...my laptop can not be restored, the data I have not been able to recover on the exchange and did not get. Therefore, here a lot depends on himself, and so I can say from myself that Yes it is safe.
