Low marketcap coin that provides something in return such as staking, yield farming are something to be looked at. I consider anything below 2000 to be a low market cap coin. With low market cap risk is larger than less volatile coin but reward is much larger.
Feg token is such low marketcap I came across. It has small marketcap and currently only listed in small exchange. You can check it out on cmc.
Only invest once you are satisfied with your token selection after doing your research.
We have to control our minds and never push ourselves to invest if we are not prepared yet. I know that some low marketcap coins that are worth for investing but we should be careful with them. But for me, I wasn't preferred to choose them but instead to look into coins that are listed in the known exchanges that will possibly give us assurance.
