Dont buy more coins, just sell a few that you have in there and try to invest that money in solid coins.
What coins do you actually own right now? You haven't posted your portfolio in there, why dont you do so? Maybe we can help you out
Oh, well, my whole portfolio is a bit "private" LOL, but the larger shares at the moment are:
Bitcoin
Ethereum
XEM
Quantstamp
Tron (did not buy a lot but now it is)
secondaries are
Neo
Monero
Waves
and quite a few others.
And a less know one that I think will be a rocket this year is Astronaut.
