Just have a look at altcoins with low cap with huge potential, check the development activities and the engagement of their social media. If the community is superb, then you are good to go
It is true that I am used to good altcoin analysis like that, I am always looking for altcoins that have good potential in the long term, even though at that time the price and volume were still low. But with the development and support of the community it will become a gem one day.
yes community support when the coin are development is a good choie to make investment on that coin, etc Dogecoin even the price is low at market but the community strong and make this can survive untill now
