judging from when Bitcoin was launched way back in Jan,3rd 2009 till date 2024 that's roughly about 15years of existence. If a project would fail it would fail long time ago so, you don't need a sooth sayer to tell you we are unstoppable.
Bitcoin keeps growing on its equity curve year after year making a great store of value today.
when the fiat money was introduced to us as a means of exchange for goods& services by the government, if the majority had not accepted it, it would have been tough. In the case of our savior Bitcoin  the majority has embraced the fantastic idea of btc to be even way much better than the one the government brought to us as it keeps adding great value to it's holders.
So to rap it all in the future I think the government would be bent to the masses opinion making this legal and we'll all be rich
