I think they are refferring to Real life Terrorists that hold gold - ones that hyjack planes. The virtual terrorist does indeed prefer to hold BTC , they generally the type to hyjack your crypto trading platform or DDOS a government buildings network until their demands are met. such a shame we cant put a stop to all types of funding to these terror groups , now there is a currency that has came out of nowhere with its own rules and personality produced by a unknown person and boasts about being an untouchable competitor in todays society ( but more so in how terrorists and criminals can move around secretive money).
