Verge went from a 500,000 to a near 700 million market cap last year, because people wanted in on a cheap solid privacy coin, and this year privacy coins will still see a rise once we hit a good bull run. Although the crypto world is unpredictable, it's likely we won't even see a quarter of the gains this year since I doubt the total crypto market cap will go 30x this year like last year, most people predict 1-2 trillion so we may have 4x gains. Anyway, while it's harder than ever now to find solid privacy coins with an extremely low market cap, like lower than zoin at 20m, I'm sure there will be some hidden gems.
Some I've found so far are hexx (3m) and aerium (700k). Also another coin that I wasn't going to share because I'm sure it's a scam like xspec is speedcash that has a 200k mc.
If you hold, found, know, or believe in any low mc privacy coins please share!
It sounds like you wish to invest into ICOs, or ICOs that hit the exchanges early.
If you do plenty research on the projects, their goals, how they wish to achieve that, how realistic and viable they are, do some research on the team behind the whole project, and the partnerships they have. After this, if you still think it is a great opportunity to invest, feel free to do that so.
But if you dont do any research or background check, and wish to invest blindly, just because a coin is low in market capitalisation, is called
gambling. You can do that, but you should be aware of the dangers behind it.
