Oh great, this ******** again.
No... cryptocurrencies are most certainly not the future. There are people, including myself, that want nothing to do with any of the horribly swaying values of hyper-speculative "commodities". Plus, I don't want my transactions recorded in a ledger. Even with tricks like coin tumblers, with enough patience and fortitude, transactions I've recorded in the ledger can be traced back to me in some way. True anonymity can only be achieved by under the table cash payments, and not using a stupid blockchain.
Even for regular every day transactions, using credit cards and other traditional methods of payment are far more convenient and less hassle than any cryptocurrency I've come across. They are faster, way more user friendly, and if I screw something up, a simple phone call to the bank will rectify any problems, like someone stealing my money using a credit card skimmer or the like. With cryptocurrency, if someone steals your goods, you're **** out of luck.
And this holier than thou argument of "banking the unbanked" coming from AnCap weirdos don't realize most folks in third world countries have much bigger problems to face. They are lucky to even survive long enough to put food on the table, let alone screw around with speculative commodities.
Finally, dealing with third parties like Coinbase kills any of the supposed utility with using cryptocurrencies in the first place. They want you tracked like a hawk if you ever expect to exchange your coins out for the price of the day in USD. Lots of insider trading going on as well as painting the tape between alts to drive the price up, get unsuspecting commoners to buy in and subsequently lose their shirts when the prices drop, rinse and repeat.
