In the wake of stringent norms on money laundering and terrorism finance, major Australian banks are closing down the accounts of bitcoin companies.

So far, the accounts of 13 digital currency providers have been closed down as Australian banks adhering to the more pressure on stricter norms on money laundering and terrorism finance.
