The question here is what could be the difference of a company holding an Bitcoin for reseve asset than an ordinary man buying holding a Bitcoin?
For the Bitcoin network, it could be seen as the next step in adoption; If large multi-million dollar companies switch to a Bitcoin standard, holding their reserve in Bitcoin, it reflects growth and trust in the asset, pushing the idea that Bitcoin can serve as a reserve currency globally, as an alternative to fiat and gold.
Few years ago, individuals investing in Bitcoin could be considered to be taken a wrong, and highly risky investment, it is still a risky investment now, but people/companies are looking beyond that now and recognizing the huge potential the network has and taking positions to stay ahead of the curve
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.
Bitcoin is risky but resistant to shocks in supply and has a finite supply, so there can only be so much in circulation; meaning it is highly resistant to inflation making it suitable for long-term investments. More large investments like these, would also improve the stability of bitcoin, making it more attractive for new investors.
