Many Coins (Blockchain) got hacked recently, 51% attack included.
Yesterday, we had a bad news from Syscoin & Binance. #SYS price was pumping so fast before #Binance went down for "maintainence" - I think Binance also got hacked. That is too bad.
It's not the blockchain. It's the Api problem you can't do anything about that. Most traders wants to create their account with the Api keys on it! i would recommended that to my friends it's very risky, i'm sorry to those investors who got hacked.
