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.
From the word "predict", there's no certainty just pure guesses in the market. So it is too obvious that no one could ever do it, market is flexible like water, the prices of bitcoin varies in time and is not stable. Volatility is the no one conflict in using it so that as of now, we are not comfortable using it instead we try to buy more. Some people are selling for their own good, and for their private purposes that's why some feel regret as they think of the possibilities. If they sell and the bitcoin price becomes high then they have nothing to hold for but to buy again in a higher price if they want. Patience is also important if you're a fan of bitcoin because when it becomes low in price and always expect and wait for a comeback. As you wait for the right time, then you can have a lot of profit.
