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 ?
If you want to keep your crypto for a long time is better to store your crypto in your own wallet, we don't know what will happens with the exchanger that we trust to store our coins in the next day (like hacked). Except if you just store your crypto for a short time for day trading, you can store your crypto in the exchanger. Make sure your exchanger is has a high-security system to protect from hackers.
