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.
