It is better to buy those coins that are on the bottom, and were previously very high that from the old price sank 5-10 times,and the project is promising,it is much more likely that it will give more profits and x, than ISO now, as all the ISO that are now out of their trample simple bottom, very much.
I agree about the coins. Now many coins were at the bottom, and not capable coins fell into the abyss and you can already understand what you can buy and what not.
