If you're a long-term investor that hopes to see gains with minimal effort then treat them like stocks.
HODL, hodl, hodl until the market picks back up, be it next week, next month, or in 2020.

If, however, you're willing to get your hands dirty and have the time for it, then day trade.
BTC and all the other coins, altcoins, and tokens are going up and down on the daily. The greatest opportunity here is for you to be aware of the market and the different tokens, read up on the news, do your technical analysis and your functional analysis.

If you choose to take the latter, you'll be sure to experience some losses, but you'll feel more in-control of your finances. If you take the former, then just kick your legs up on the table, sip on your favorite beverage, and relax... the market's bound to pick up, eventually.
