In principle, $ 25 is not a lot of money, I drink more in a bar. Probably it is worth taking 100 coins, and maybe really your project will show a good result. Eh! "was not to was" as they say in my homeland. I take buy 100 coins.
I agree that an investment of $ 25 is a very small amount. This is a couple of mugs of beer and smoked sausage)))
But on the other hand, invested 25 dollars on what kind of earnings can you expect? At the minimum, respectively.
In fact, for cryptocurrency $ 25 is almost not money, but everyone invests as much as he has
