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 ?
Always there are risks. I hold cryptocurrency at the exchange and some coins on MEW e-wallet too. Though I know that it is up to the end not safe. The best method will buy the hardware purse. It is the safest method!
