What attracts people to altcoins is their generosity when it comes to spending their time in exchange for tokens or investing $100 and getting $10,000 in profit. In this respect, altcoins are much better than bitcoin and that's why they attract a huge number of users. In cryptocurrency people, in the main, come for earnings. It is quite difficult to make money with bitcoin, it is slow and expensive in terms of growth potential. Altcoins are more flexible in this respect and are more suitable for all kinds of speculation and quick enrichment.
I do not think that it would be common to make that type of profit, and it is rare for anyone to get that type of return as well. Not only we have very few tokens that go up like that, we also have very few people that get in at the bottom and get out at the top like that as well.
So all in all the reason is not that because people make that type of profit differently, and it is not going to be easy neither, we are not going to end up with a terrible situation, it's going to end up a bit different. Of course this is going to end up with a bit of trouble but at the end of the day you could still do that and I believe that's what people like in this situation, they like that there is a potential of making that kind of return.
I agree with you that a very small percentage of investors can make a profit of $10,000 with a deposit of only $100. But it is worth considering that it is impossible to get such profit in bitcoin, unless you are engaged in trading or margin trading. You can get such profit in altcoin sector by participating in various activities, such as retrodrops or testnet. The chance is minimal, but it is there.
