Every day a lot of new coins appear but not all of them will be profitable.
A lot depends how useful coin will be in the future and how big community of users it will have.
It is true that new coins come in the market every day, but one or two of them may be solid projects and the rest are useless projects. A solid project can change your life, and it requires knowledge of the crypto market, as well as knowledge of how to find potential coins for the future. The crypto market will give you a lot of opportunities, now it is entirely up to you how you use that opportunity.
Investors who cannot take advantage of market opportunities and are attracted to various fake trends cannot stay in the market for long.
