- Check the coinmarketcap.com and choose ones with high volume
- Check the projects
- Check the chart, if it is pumped, don't buy, wait
- Check the chart, if it is dumping, wait low volatility
Not sure about coinmarketcap. I know at least two blilliant US-based project with strong team and coinmarketcap have actually denied a listing and just haven't replied
I agree with You completely. Coinmarketcap is not a level for determining the quality of a token. I know a lot of coins that without the help of Coinmarketcap have a good trading and profit

as a new trader of course not so know about the coins that have a good quality to buy, it is not only in Coinmarketcap alone for us to know or find a coin that has a good potential for us to buy, many also other altcoin which also has good quality, and the coin is not listed in Coinmarketcap, maybe in other exchanges we can also know the coin is high quality and has a high volume, and for new traders I personally often see the graph for me decided to buy and sell.
For this, better research is always appreciated. The thing is, we all are working on this bitcoin and some are doing on some other altcoins as well. These coins are of such big potential that we can change the whole life style by using them and earning form them in a drastic way. So better is to learn what the ways are and how to do things. Only then you would be able to make handsome money.
