If the COVID-19 panic continue while no vaccination is detected there's totally the chance of bitcoin market to downtrend to the $3000 even during halving because more business will be close including some other activities and some crypto investors/traders will have no choice than to sell some of their holding.
There is still another month to find a vaccine to treat Covid-19 because halving will occur in May I think there is still time for scientists to find it.
I do not expect bitcoin will fall again to the bottom let alone reach $ 3000. Let's see what will happen even though there is a lockdown happening in various countries, but they are still confident about bitcoin that will be able to fly high to go up.
Just forget about any vaccine in the next three - six months. Bitcoin halving will occur in May so before even the stabilisation of the pandemic around the globe.
