1. Here on the forum, you will hear only one answer - BTC. Only Investors from the traditional financial sector can invest in MSTR, for whom BTC is something incomprehensible, but on which they want to earn (indirectly) extra money. MSTR provides this opportunity for such cautious investors, but in the eyes of the BTC-community it will forever remain like trash. Choosing MSTR instead of BTC is like choosing a rubber woman instead of a real.
2. This is the same as asking whether the secondary and by-product will be more valuable than the original one. I guess not.
3. Controversial issue. On the one hand, when investing in MSTR, an intermediary appears who can both ruin everything and be an additional guarantor of reliability. I think it’s only because of the second factor that this asset will be in demand.
