There are many examples of hyperinflation, and there have even been cases in history when buying gold did not save people from this, because the state simply seized all the gold from the population.
Now, in the context of the global crisis, inflation has become a problem for everyone, even developed countries feel its impact, and in less developed countries the situation is even worse. Therefore yes, bitcoin in our time is an excellent tool for preserving the value of our funds. We live in a unique time, and whoever understands this and buys bitcoin will get a very good advantage, and will be able to survive most of the possible crises.
If the government seized Gold in the past, what makes you think it won't "seize" Bitcoin in the future? More people are turning to crypto/Blockchain tech as Fiat currencies lose traction due to ever-increasing inflation rates. Central banks' efforts to control inflation have been widely unsuccessful, making BTC a more attractive alternative to existing Fiat.
If the government outlaws the possesion of Bitcoin, that doesn't mean it's the end of the world. The pioneer cryptocurrency is decentralized and censorship-resistant, so people will find a way to bypass government restrictions. The government will have no other choice but to join the revolution. Who knows if BTC is poised to take over the world as the leading reserve currency? Just my thoughts
