Banks and Wall Street will never die as well as centralization. They'll adapt to the new circumstances and keep screwing people over and rake the profits. They have all the money and connections to do that. They're way ahead of the curve if you ask me.
Look at the leofinance and hive users for instance. Most of them are smart and crypto educated and know their stuff. They know markets, charts, trends. But unfortunately, most are broke and all they can do is talk. Swing trading, arbitrage trading, chasing low fees, and low gas...? For 8 bucks?
It's sad but that's what it is. And even if they'll score with their alt bags they'll blow the money anyway.
We just can't change human nature with the switch.
I really hope I'm wrong but I just try to be realistic here.
