Obviously I can't speak for the BSV peeps, but the way I see it: they've been so financially and emotionally invested in Craig Wright and BSV that they're pretty much in denial. I assume they've lost so much money(in BTC terms) if it's the case that they've converted their BTC to BSV, that it would be immensely painful for them to admit defeat, and accept the tremendous loss.
...while at the same time hanging on in the hopes that their Satoshi will be
proven (wright) in court.
The loyal supporters definitely see injustices to Wrights claim all the time and
100% support his claims in order to validate their blind following and
get back their investment.
It must be mightily stressful watching your BSV investment slowly melt
away as CSW's claim slowly melts away. There are those who are certainly heavily
invested who just cannot walk away.
I wonder how many secretly realise now that it was all a hoax?
