Hopefully it's not true. Recently, I have been reading lots of articles and claims that myetherwallet is not safe anymore, and that many hackers have cracked how you invade and steal coins that are held in e-wallet sponsored by it. However, I think that it is still one of the best wallet around to hold coins, I still have not seen any reliable and true accounts of hacked myetherwallets except those that have been scammed or victimized through shady enrollments like scam airdrops. Thus, I would still believe that the people behind this wallet would do something to safeguard the coins of the many people using it.
