The market growth is promising and the same is being related with different things. This is so common, whenever there happens something positive with bitcoin people start to relate the growth with any of the incident happening around the market. Covid-19 vaccine will not make any impact upon the cryptospace, because the market isn't reactive to sentiments.
sometimes people quickly see the good or bad movement of bitcoin, it will be linked to something that was there at that time, like today with the covid-19 and expansion of the distribution of existing vaccines, even though we know directly that there is no relationship whatsoever between bitcoin and that matter. just because the moment just happens to be the same then the observer insists that there is a connection, even though it doesn't exist at all.
covid 19 is designed to destroy the economies of many countries. with so many countries spending a lot of money, to solve it.
and the covid 19 vaccine has nothing to do with crypto at all
yes, I strongly agree from what you said, that indeed with this pandemic, almost all affected countries will experience economic difficulties because of the pandemic. because there is no income into the state treasury because many companies have to stop production and there are no activities that can get income from taxes. In fact, the state has to prepare finances from unexpected budgets to be used for all the needs caused by this pandemic. I hope this pandemic will pass soon.
but all of that will not have a direct relationship to the development of bitcoin itself because it is clearly different in designation and system.
