The site requires too much information to verify. My bank refuses to send out paper statement, they only prodive PDF

Poloniek really destroyed my trade

I had XRP at 6200, was about to sell at 7000 for a quick profit; then the site froze, now I still hold them... can't sell at 4000.
Just after the freeze, XRP was so cheap to grab. Yet I had no BTC left. IT's the salt to the wound cuz I knew for sure that price would jump back up to about 6xxx, which was what happened. Depositing bitcoin takes some time, and I missed that opportunity.

Now I'm stuck with XRP. I will leave the coins there and comeback later I guess

Imagine if I could sell all XRP at 7000 and the crash happened. I could hit the bank with that opportunity. Unfortunately, I'm on the other end of the knife

ISn't Polo is the biggest exchange market out there according to the Coinmarketcap data?
If it's big, it must be good

Bitcoin exchange business regulation?
I do not see any Australia business go global as of now. Is there any restriction?

Plus, If bitcoin is a commodity, what kind of document should we keep for tax filing purpose? We have to prove how much we gain through bitcoin trading.thanks

I think only capital tax is concerned because bitcoin is just a commodity, an asset. What document should we keep for tax filing then?

Another question, Why do Bitcoin exchange business in Australia do not go global? is there anything that stops them?
