Plenty of remainer short sellers, George Soros for one.Speculators, short sellers, hft etc.
Long term trends is what matters.
He raked in Billions in Brit tax payers money when he shorted sterling in the Black Friday debacle years ago.
He has used some that money to fund remainer agitators in their attempts to overthrow democracy in the UK.
Soros and others like him make money out of chaos, instability tends make currencies go up and down like a whores knickers, that's when there is money to be made.
