I am not BTC maxi. But I have some BTC. Reasoning is probabilistic:

I *know*, 100% sure, fiat will go to shit, I am already seing my fiat evaporate from the bank (inflation numbers are fake) in Brazil, I am losing ~10%/year, besides being taxed to death. I am sure in 10 y I will be much poorer (and everybody around me too). And in 20y it will be even worse. The descent has been already happening for decades.

I am not 100% sure BTC will be confiscated, or if the government will be smart enough to close all in/off ramps into tax hell and draconian persecution. Probably it will. But the government may be too incompetent, corrupt ( then I have to pay bribes ) or just colapse before that. Or at least, BTC wealth may last a few years after fiat evaporates.

By 'confiscate' I do not mean just taking BTC from exchanges. They can track it, find you, and give a tip to the cartels. Then bandits go to your house, cut your children's fingers untill you give them the keys. Government boys will get their share.
