Same here. I have never owned an NES. We went Atari 2600, Commodore 64, Sega Master System, Amiga, Sega Genesis, Saturn, PC, Dreamcast, GameCube and Playstation 2. (I wasn’t a kid by the last few of course). I’ve played some Nintendo console games in emulation but have never owned one aside from the GameCube. And agreed, Phantasy Star is awesome.

As far as transactions, yes, something like Visa takes way less than Bitcoin. For HFT compared to crypto, who knows, but one thing they’re not doing is something intentionally wasteful like proof of work.
