Depends. It's more risky than buying bitcoin, but it's better if you're bullish. MSTR is also a company, so some people might prefer it over bitcoin. I'm not sure exactly what they do, I think they sell servers or something. And I'm not sure how profitable they are, but I haven't heard anything bad about the company. Personally, I find leveraged ETFs to be too risky, but MSTR isn't exactly a leveraged ETF. It's safer than a leveraged ETF because it is an actual company.
