Would you still recommend to friends to buy Bitcoin?

I used to recommend it because it is simply "the biggest crypto currency," so what can possibly go too wrong?

However, now with Microstrategy looking more and more like a ponzi I'm worried that once they blow up I might regret my endorsement

It’s too late in the cycle to really recommend buying anything. You should tell them to wait a year or two when Bitcoin has corrected. Buying now is likely very close to the cycle top. But yes, Bitcoin still king. MicroStrategy just needs the price to be higher every four years because of how it’s all structured
