Sounds interesting.
Just to clarify - If I am a UK resident and I buy the wine with BTC and it remains in the bonded warehouse and then I choose to sell it for GBP at a later date there is no capital gains tax or income tax to pay on the profit?
Can I move the wine to another bonded warehouse in a different country?
presumably yr still liable for capital gains on any BTC/Altcoin gains that u may have made with the coins used to buy the wine!?
I think that is debatable - I just had a look how HMRC deal with bitcoin and the interesting thing is this
"If a transaction is considered speculative, it may not be liable to tax at all."

Otherwise, if it is not speculative then you are liable for capital gains.
