You're being given the opportunity to buy the future world reserve currency IMO. Altcoin USD gains won't keep pace with that in the long term. That said I'm still selling the alts that I bought when I first got into the space, so I guess you could say I'm already diversified in that sense. I expect that I'll sell all or nearly all of those
As for buying BTC... I just DCA in every month. I have high conviction and see BTC like a piggy-bank. I vary how much I buy depending on what I need money for, but I wouldn't adjust that due to Bitcoin price. I believe that its a good value at just about any USD cost. I'm not trading, I buy and hold things I think are valuable.
Data I've seen suggests that is not the case. However I don't know for sure so I won't bother arguing about who holds the coins.
I would be willing to argue that I'm less concerned about who owns the MONEY and more concerned about who controls the SYSTEM. Nobody can print infinite Bitcoin and hand it to their friends. The existing coins will distribute as they are spent and will be disburse more widely with time. This has already been demonstrated. Our current system allows a small, centralized, group of oligarchs create new money whenever it best suits them. They own most of the assets that are denominated in this currency as well so not only do they get the newly minted currency first, the resulting inflation also pumps their bags.
How could Bitcoin be more corrupt than that?
Also, the rich hold all the money in our current system too:
The most recent data from the Federal Reserve shows that the top 1% wealthiest Americans have a collective net worth of about $36.2 trillion.
