There will be a comeback but I don't think that we can really predict it because of the market's volatility, plus the external factors such as this pandemic and rules and regulation that are implemented.
No one could ever predict the market though, but the possibility of a bounce back is huge considering how optimistic the people for the block halving. The pandemic don't have direct effect on Cryptocurrency unlike the stocks. Look at how the market was moving for the past few days, it's moving within the $6,000 range and It didn't went below $4,000. If there is no block halving this year, Bitcoin could've been in a worse figure by now.
