Try to research by yourself so you can find the right coins. There are many possibilities for every coin to increase 10 times to 100 times in the next years, but it is difficult to know precisely because every coin has the same chance. So after you get much suggestion from here, better you make your research so you can find the coins to buy. But remember, never go all in with the coins because you need to split or leave some balance in your account, just in case if the worst thing will happen later.
