If you are actively following them then maybe you can decide on what to do.
It's not about the price but you can gamble if they are currently active in the development and doing something to create good liquidity on their respective coins. Not a financial advice but just stating one of my preferred factors when choosing low cap coins.
I used to gamble too on low market cap coins before and so far, the results are good. Plan carefully if you are really interested in those coins.
currently looking for a low cap coin that been in the market for some time, to ensure a stable price. For a long run.
They could not coz they were crap coins. SNGLS and SNM are not worth to invest. You must find another gem. I have ever read someone created a thread about buying the old garbage coin and he was getting lost caused by it goes even deeper. Try to search for another gem that is not yet increasing. It's maybe like adex or something else that makes you interesting and it's still underrated.
SNGLS and SNM have no solid product. It's better if you can gamble with the top 200 coins.
but what exactly is the reason that they are crap coins. Your answer isnt very helpful
