MSTR is simply a company seeking to grow their bitcoin in their treasury. They represent an investment in equity - nothing special, except they are early. In future I hope lots of other companies will present a similar proposition - but the opportunity cost of these choices will always be holding the btc. Companies will definitely have to demonstrate a positive risk adjusted proposition for individuals to invest.
This is a good take. Buying MSTR is not a proxy for buying Bitcoin. If you want to invest in companies to get higher returns, that’s for you to decide! But I am looking to save. Hence, Bitcoin.
