The search for potential small capitalization, you can use the aggregate price sites like coingecko or coinmarketcap. You can use coinmarketcap with the "Trending / Recently Added" function to check the list of new coins added. In order to filter out potential growth currencies, you should set criteria such as.
New to coinmarketcap less than 20 days.
Trading volume is over 1 million USD.
Market capitalization of $ 5-25 million.
Then, you select a list of currencies that meet your criteria.
Not bad but remember those coins can give great profits especially if you select the right coin but at the same time things are not so simple anymore, just a few years ago you could select almost any coin and you could have gotten profits thanks to the bull market and since that is going to take a lot of time to appear again then I am not so sure this is the moment to take such a high risk.
Thanks for sharing, these are clever ways to find new projects that have not been on anyones radar. But I would wait until we get into a bull market before playing with these ones. Depending how much longer the bear market lasts...few of these might survive.
