Humans learned nothing from history
If they did they would know.
Next war and financial crisis start with Europe when eu bonds crashing the war starting to little cover up and hide financial system and bond market ponzi scheme.
It will affecting the rich ones, one bank will collapse and without bail out.
But let's be realistic If you own like mil or bil of $€ in bank it's not protected you own estimated value what you think you own try to cash out 1 mil $€ in bank ? Its difficult you can't, that's why gold crypto and all other tangible assets will increase in their value because wealthy want to keep less money in bank.
Many people who are wealthy not smart by finances they don't have no idea that they their wealth could go over night.
Talking about UK - they did sent gold out of UK and made strong cryptocurrency restrictions and brexit so they have capital control and prevent Capital outflow from UK If they woul't do that people would exchange uk assets into crypto or gold in hords and that would make uk to crash.

But wich bank willl trigger the next crash, i don't say this but it will be next "too big to fall" thing. Many rich ones will lose a lot money but what can you really lose If you never had lol ? So all is fair !!
People who don't update their brains will be always in down. It's a greatest and biggest wealth transfer in history If you on the wrong side all will be dumped on you If on right side you hit the JACKPOT.
