After the market turns around, I am sure that many coins/tokens will show growth 10 times. In 2018, projects were developing their product, many left this market for various reasons. Remains the best projects.
I think we're spoiled by 2017 and our expectations are way too high.
Realistically, I'll love it if we simply beat the stock market.
Those coins that lost 90%+ of their value were all overpriced, not sure why they'd be back to previous prices.
Progress will bring them back to the high that they've reached before and even break and create a new one we are inside crypto market and there's always a chance bringing everything to go high, everything will start with bitcoin and afterwards those quality coins who will survive this downfall will go along with bitcoin again, hard to say but for me tops 20 coins will have a good chance to bounce back.
