I'm not sure if this is the first time we have heard a company making bitcoin as reserve assets, but I would say that this is welcoming and pushing the boundaries of bitcoin as a store of value.
Of course it isn't the first time, but i think this one is the biggest with company running out of the crypto market. We should also consider that MicroStrategy is one of the biggest companies in the world today having millions of shares traded actions in NASDAQ stock market.But global adoption? I would say no. Besides adoption has slowly been taking place already, even in this current pandemic situation.
What i meant by Global adoption is that more companies follow the same strategy, especially with the accumulated issues with us dollar and other currencies used for reserves. This should also include countries living in continuous liquidity crisis.
