Metropolitan hasn’t said whether it plans to restore the service or not. It’s also unclear what might happen to the money that existing international clients have in the bank. Fears of frozen assets shook the cryptocurrency community.

I haven't seen any announcements from Coinbase or GDAX about halting wires from their international customers. So maybe they have alternatives in place already.
The author notes that there are other cryptocurrency-oriented banks that can likely fill the void, like Silvergate Bank and Cross River Bank. This is just one intermediary bank. I'll become more concerned if we see similar moves from competing banks. That would suggest government/regulatory action is on the way.
