as from now there's no tackle application for contact tracing for covid 19 we have now is to test who the positive or negative on covid 19 and thats we called test kit.. and i think there's have bo conection between bitcoin and covid 19 to trace or detect who's the infected of virus..
I don't think there will be too much impact between COVID-19 and bitcoin unless the bitcoin holders take the necessary actions to sell food during the lockdown period in their respective countries, of course this also has a slight impact on the price of bitcoin.
Because as we know halving for this year is one of the different experiences in previous years, where this time halving prices tend to decline compared to strengthening the assignment of course this is also influenced by COVID-19, but in terms of who is positively affected and negative of each person it is indeed difficult to detect unless we go to the hospital.
