We heard that crypto is often used for terrorist funding, but according to IOCTA in 2018, such an assumption is wrong.
Today, the popularity of Bitcoin is getting better, but the relationship with terrorist funding, they prefer the classic method of transferring through banks.
so, terrorist groups that use bitcoin are only low level transactions.
the bank print money through bonds so bank has no difference with terrorist but they do it in legal ways, you see the actual physical fiat currencies is lower compared to digital money created from loans and debt.
