In 2017 people saw how the price of altcoins raise and they believed in altcoins. Now there are some successful projects but the price of most altcoins dropped to zero. That is why investors stopped to trust altcoins.
It's not only altcoins, the whole crypto market now have the same situation. The 2 years bearish market still not end, so we can't hope for the rising again of altcoins. We need a stable market first, and then the altcoin projects with real product and users. Seem like Romad is doing this way.
Stabilization of cryptocurrency market is very important. It is very hard to develop when cryptocurrency market falls.
