I have lost a lot of money in coins other than Steem and EOS right now.
You lose $0 if you hold those coins and wait for the market to turn around.
Why did you sell them all? If you did, then yes, you lost money.
If not, just hold and wait. Maybe it will take 6 months but the value might come back.
Bitcoin has had huge and massive drops like this quite a few times since 2009. You just have to zoom into the charts up close to see them.
XRP and ADA are bleeding out hardcore. ETH is the only one holding up but even ETH is poised to drop a lot.
