Dude!! This is amazing!!!
One of the reasons I really like crypto is the 'currency without borders ' aspect. Eventually we'll move back to Australia. Transferring money across from Australia was a slow, heavily fee'd process, with incredible restrictions. We bought a house in the US but our deposit money was in Australia. It took me a week and heaps of phone calls to find an adequate process.. and even then it took 5 seperate transactions as banks have daily limits.
I think we'll rent out this place when we leave, so crypto will be our bridging finances when we move back...
I have no idea how this will work tax-wise since investments have all been made from mny US income, but we have an excellent Australian accountant who will no doubt be excited to tackle it.
I have a client like you. Shes and Aussie who works for the UN, earns all her cash in USD, but still pays Australian taxes. She's a nightmare. Lucky she's super hot :)
