I also think that the company have reserve asset that can accommodate an event where their Reserve Cash suffer a great loss such as Bitcoin price crash. I believe their company had sorted it out since I am sure they know how risky it is to use BTC as their Company Cash Reserve. I also believe that they are bullish in Bitcoin hoping that their Cash reserve will balloon in value one day.
Since for me, it is a purely risky since it is company and a lot of people are relying on the company itself. But somehow, there's also a lot of possibility that their reserve will generate a huge returns for them if ever Bitcoin will continue to increase it's price.
Surely it is an advantage on the side of the company because apart from bitcoin that is bought as an asset which is like another investment or savings made by the company, the company also has other sources of income different from bitcoin. That is the source of generating money to run, finance and payment of salaries. Buying bitcoin will not be risky but advantage.
Well it is both an advantage and disadvantage if we look at its two side. But I believe the company's move on this relies on their calculated risk management.
