10 USd is a small amount, but if you want to hope for luck then you have to choose coin-based tokens and have low prices. You can speculate by buying coins at pres-sale so that you will get a discounted discount. But it is worth remembering that investing in a new and still unknown coin is quite risky. Many coins are circulating and that is your choice, that's why the analysis function and making observations on ICO projects are important.
