bitcoin is still in his infancy still a long way to go before it will be accepted seriously
Not to mention some of us might be dead by 2030, and I want to buy for my BTC something before I die and not 'hold' forever.
Yes the powers that be will attack and try to censor Bitcoin all over the world, but even then, it will become the #1 way to run an alternative economy, and underground economy has billions on it, so with or without the consent of governments, holders are holding something that will be very desired in the future no matter what happens at a regulation level.
