Do cost averaging on well stablish crypto coins like ETH, LTC or NEO and BTC and hold your coins for 1-2 years. Almost all newbies who invest here on crypto want to get rich quick and after they see that the market is falling they panic. If you're a long-term holder crypto crashes are just normal and you won't even get mad about it. Long story short buy and hold.
I agree with Daddyj2 on this for the most part. Basically, since we're currently going sideways, the way forward is to remind yourselves that this is still the beginning for crypto. Though he suggests to hold your coins for 1-2 years, I reckon it a wise move to consider a slightly further outlook on things, such as holding with a 5-10 yr plan in mind. It takes years for new technologies to really make it to the mainstream and crypto is no different. When the kinks are all worked out and it's easy for your parents to buy in / use easily, that's when we'll all be laughing.
