I'm specifically interested in very low market cap projects with extremely high potential to explode in a bull market.

I've gather 3 projects so far that are under 10 million dollar market caps now but rose over 60x-100x in a matter of days during the December/January bull markets. They are now back to their pre-bubble prices, for the most part.

Upfiring - Incentivized P2P file-sharing where seeders get paid to seed/share files. Also has the lowest market cap on this list at around 2 million, so likely the highest potential for returns if the project is successful. Active on reddit: https://www.reddit.com/r/Upfiring

COSS - Exchange that still needs a lot of work, but has potential in the future to be really useful. Shares 50% of profits with token holders and has trading promos. Also active on reddit: https://www.reddit.com/r/CossIO

Oyster - The worst performing project on this list since January, price-wise. Deals with file-uploading using IOTA and ETH. Has really bottomed out recently, and I'm not sure if this one will ever move, but it's worth buying a little just in case it ever surpasses ATH imo.

I've recently picked up these and am holding. What do you think of these projects/any more suggestions for micro-cap projects with high potential to add to the list? No new projects or ICOs, please. I'm really only interested in established projects that have been around since 2017 or earlier.
