Of course, everything can be. Perhaps these coins or at least one of them will rise in price just like bitcoin. Although, the chances are not so much. I think that the more the crypto currency develops, the less probability it will be to increase its price by millions of times. In my opinion, the period of the "wild" crypto currency is already passing.
Some cryptocurrencies are dropped down to oblivion, there is no assurance of those coins to pump that big after 10 years, but there is still a probability that it can happen in the future. It this case, do not lose hope, just believe in it, you just invest for about 10 dollars and you doesn't lose a big amount if it not succeed.
