If you are truly doing it as a hobby then continue doing what you have been up until now. Hop around to a bunch of different coins and accumulate a small stack of each. When the market returns in 1-2 years hopefully some of the coins you mined become winners.

Just be sure to mine coins with either low difficulties or large block rewards so you can accumulate a reasonable amount of each in a short amount of time. Maybe spend 1-2 weeks on each coin then move on.

I would not worry about the current profitability as whatever you pick it is going to be crap in the current market. Instead just focus on having fun and trying to accumulate a bunch of different coins that look like they may have future potential.
