You have to stop checking prices every second, otherwise you will go crazy. Read up, buy some coins which appear to be logical buys, and just HOLD. Do nothing, don't try to day trade, don't try to outsmart the market. Never panic buy and never panic sell. Up until now, every major coin has bounced back from drops, so unless you have invested in absolutely useless coins (which, based on your portfolio, you haven't), just be patient and don't panic, even if your numbers are red right now.
Exactly, RESEARCH your investments and purchase based on same. Put in your wallet and forget about it. I just started recently and selected my investments based on reading a variety of sources. It's too easy to get caught up in the hype. No one can predict the market, if you are planning to day trade then you may lose your ass.
I invest based on real world applications that a given coin has the possibility of providing a solution to current issues in the business sector it affects.
