So there's 6000+ coins out there. Look at the max supply. A coin with a large max supply and rapid emission of new coins will most likely never surge in value. This is because the worlds total capital is divided with so many optional coins. The larger the supply, the more capital it needs to spike in value. Even Bitcoin with a max supply of only 21 million needed massive amount of capital to get where it is now. So any coin with double that, will need the double amount of capital to get to the same place. So with so many options out there if you want good value pump. Look for something with max supply of only like 1 million. (which of course needs to have a utility too to stay in growing demand)
I do but not after I looked in their roadmap, their platform and people behind the team, the supply is the least of my concern even if the supply only has 10 million, but if the project can turn out to be useless, usage should be the high priority it is something that defines the project, two examples mentioned by others are Ripple, Ethereum and Doge
