Though you'll find less people outside the crypto community accepting crypto payments for such large sum.
If the OP makes up a business in a country where bitcoin is popular and people use it freely then they wont face problems in getting payments in it and interconversion between local fiat and crypto. This type of a system is still not popular in most countries.
We know that it'll be a good deal to receive payments in crypto especially when the market is down.
From the business point of view it is better if payment are pegged to USD value of bitcoin. That way it does allow the person to accumulate more crypto, since everyone likes to inflate their bags whenever possible.
But there are also quite a lot of legalities you have to arrange as well if you're not buying a local property.
That is the main problem here. I dont see any solution here at all other than bribing the authorities (just kidding).
