$0 BTC is a funny concept. There are plenty of people who would buy up all available BTC at the right price. There are fewer than 21,000,000.
If either party values their wealth in some fiat currency, then of course you are right the crypto is converted at one end or the other.
However, some people do transact in crypto with no fiat involvement. This happens when both parties value their wealth in crypto. There are people with piles of ETH that they bought at $0.31 and there are people who bought piles of BTC when it was <$250. They don't need to convert to fiat or calculate some fiat pretend value of their transaction. They can transact in either of their native currencies and convert between them without ever caring about USD.
I believe that exactly the same will happen between RUB and CNY. No need to "dollarise" everything. It's taken 51 years since Nixon accelerated the dollar's debasement, but finally the world is moving on.
you can't pay rent in crypto if there would be no exchange into fiat.Fiat is the currency which is accepted not crypto.Crypto can be only used as there are currently instant exchanges into fiat
