If your tokens are suffering bad losses, you need to re-evaluate the token you're holding and try to see if it'll recover in the future or if its dead. Remember, most alts promise a lot but are ultimately worthless.
HODL good altcoins. There's a few that have bottomed out and are a prime opportunity to invest in now - alts like Ambrosus (AMB). Always remember to do in-depth research to differentiate the good from the bad.
