Yes, there is a huge chance for altcoins to recover their prices, but based on the previous charts the price of Bitcoin will boom in 2021 because after halving the chances of increasing Bitcoin price will be huge. We might see many developments release in the coming year and it will help to increase the price like 2017.
Unfortunately so far the development part didn't help with the adoption. We need a convenient wallet that lets you use both crypto and fiat. If Revolut for example stopped being greedy and incorporated crypto transfers already then it would be a huge thing and surely impact the price and longterm success probability.
