Vast majority of humans on this planet have no money to invest, there is indeed a heavy market cap, especially since most people work 40 hours a week and live paycheck to paycheck. I am not bullish on cryptocurrency at all, but congrats to the people getting wealthy off of it. I mined Bitcoin in 2012 with a 7990, I stopped before I had finished two coins, just figured it would go nowhere, also there is something very sad that we had to pollute the earth even more to make fake money, lol. Those mining machines are no joke on wattage in Chinese farming mills. Water wars will start up within 30 years as global warming is increasing faster than anyone predicted, Bitcoin will probably do well overall, but governments are always going to remain king, private property protection, laws for a normal society to function, etc... government is here to stay... Bitcoin is flourishing for now, but when people realize how little protection they have (bitcoin ATM's come to mind)... well might as well rob those people instead of robbing black market credit cards, transfer those funds to monero coin then back out to a new bitcoin wallet, basically criminals will become invincible. I'll stick with fiat currency for now, like it or not, if fiat currency ever bursts none of us will be able to afford to eat and your bitcoin won't buy you any food either, everything will collapse. lol thats why it will never collapse, fiat currency, while flawed, everyone is in debt to everyone else, its just too big to fail. and if it does fail... well good luck finding food workers willing to work for $8 bucks an hour to ship out your veggies and fruits that will cost $60 an ounce that no one can afford, thats what happens when fiat bursts... hence why it will never burst. we all rely on eachother. bitcoin is a pyramid scheme, it will only continue to rise as it has buyers, no mining exists anymore. and only the rich can invest. so there is indeed a cap, as that leaves out 90% of the human population.
