Dash is one of the most expensive passive income generating coin through staking. If you haven't heard about it, you don't have to search for it. Dash is still big as other altcoins that are being heard by the community.

I see these coins rise but there's no certainty if they will rise against bitcoin. The market is hard to predict but if you are holding or bought Dash, you just bought a good altcoin. I'll be of the same opinion with zcash.
