What is this? a Memecoin?

No,

this is MSTR, the Microstrategy's stock

guided by the famous Michael Saylor

I think that the first ever ETF on Bitcoin was MSTR

Why?

Because this company is heavily invested in Bitcoin.

Michael continues to make debt to buy BTC making his company dangerously exposed to this risk-on asset.

At the moment investors like it and it's a way to invest indirectly also in BTC

Is he crazy or he is a visionary?

Only time can tell...
