I think most altcoins are in for a sad fate. You can see the recent trend of delisting tokens from many exchanges and, perhaps, this is true. Security tokens are generally one big question mark, if the SEC starts to analyze, then most of these assets are doomed. Therefore, now normal exchange doesn't list such projects. Who holds, at the first opportunity, fix the profit (at least on decentralized exchanges) and buy more stable assets. Utility tokens are also unlikely to bring big profits in the long term, in fact it is coupons for a certain service and I don't really understand how they can be traded on exchanges and grow in price tenfold.
