Two lowercap projects for me, which are both privacy coins are

Spectrecoin (XSPEC) - released stealth staking on a trustless set up so has something unique. Max supply of 21million so loads of growth potential

PRiVCY (PRIV) - very low marketcap, currently around 44sats. Active development and community is growing by the day. When fomo kicks in I can see this one rocketing, max supply of 30million

 Heck them both out for yourself, devs and core team are active on discord for both projects
