If your fund are limited, I'd suggest giving cloud mining a shot.  Hashflare is great because it pays out daily and allows you to reinvest your earnings automatically.  If you are a believer that cryptos will continue to go up in value and are in this for the long haul, mining is a great way to go.

The other option is to become more involved on Steemit, provide quality comments, post great material, earn Steem/SBD, and exchange some of it for cryptos every now and then.
