Yesterday, I logged into my Coinbase account after a long time and ... It's empty,
I have a small amount BCH and BTC there. 2 transactions were just made and sent all my BCH and BTC to somewhere.
Before that, I did not recieve any email, or 2FA SMS.
Now I lost all and dont know why.
I think you have not activated it long ago. Everything seems to be down and the hackers are easily invaded. Most investors often lose their money because they do not often check their wallets.
I advise you to check your wallet every day to avoid any risk.
Checking your wallet everyday will only permit you to know the exact date the loss occurred. Checking your wallet everyday doesn't prevent the hacker from getting your money.
