Spent a few years inside two bigly banks years ago ... but small compared to what they have evolved to now.
Moving 50 Billion each day through the Federal Reserve's central banking system (warts and all) was small 'taters even back then.
That system made the US economy second to none.... and it sucks in many ways
It's all digital imo ... 1s and 0s ... even gold, etc. for the most part and one big ol' Three Card Monte shell game.
Crypto is TCM on $teroid$ tho
I was a sucker in NYC once ... as a teen ... lost $40
