As long as you remember that small cap alts truly are speculative, hence high risk and potential high reward, then I think there are definitely some gems worth looking into. Based on the interesting posts here, I'll look into XSN a bit more.

I'll admit I've been holding Spectrecoin for some time. I've got price targets in mind, but it's also a coin I don't think I'd ever fully trade out of since it does what I value in a cryptocurrency and it does them well: privacy and anonymous staking. Setting up my raspberry pi to stake it too to make it a simple and efficient way to keep accumulating. Plus it's got mobile wallets in development and cold staking on the horizon, so there are still factors that could lead to growth in interest and usage. The developers are available on Discord for discussion and I've seen them put in plenty of work over the course of 2018-2019.

So yes, XSPEC is my pick and I think it has a solid future. What other coins are you folks interested in? Good stuff in this thread.
