does anyone have any statistics % or information about how many people either succeed or fail (lose their money) doing trading in cryptocurrencies, also the people who are working on their own coin project( not a scam project)?
That kind of statistics can nowhere be found because it's hard to track those as it needs data from all exchanges on which are some are decentralized.
There are people succeeding and losing and that's the reality. I don't know what kind of benefits or advantages you will get if you saw the stats you are looking for. Just do your best to it's fullest in order to gain profits in crypto over time.
