You need to look at the market cap because if a coin has a very large supply then the price will be cheap. Cardano is cheap because it has a large supply, but equally it is a good project and therefore has a high market cap relative to the other coins.
That's why I do go for low circulating supply, whenever I want to invest in any good project. Large circulating supply takes a whole lot of time before you see change in price. The price is always stagnant at a price of 0.0001, it also fluctuates below those range and it's not encouraging
If you choose the low circulation tokens/coins, then it will go down then what you are seeing now. Please do not analyze like there are plenty pressure over the crypto investors due to recent dumps in the marketplace.
We need to check the value and high circulation, multiple exchanges and fame. These things only make the coins grow and pull the more investments.
