https://cointelegraph.com/news/bitcoin-rent-agreement-argentina-landlord-tenant one would conclude adoption is striving in Argentina. Paying for a house with bitcoin sounds to me a mistake or lack of financial knowledge. Bitcoin is better than Fiat. Bitcoin increases in value and fiat faces inflation. Why then would one spend Bitcoin instead of fiat on a house rent which may expire in few years? Accommodating the Bitcoin can birth the person more money to pay his next house rent. But fiat wouldn't add any interest in the bank. Moreover the house owner will not hold the Bitcoin.
We can say it's a good thing and a waste for the tenant, it just depends on our perspective and actually it will be a good one for Bitcoin since it will increase Bitcoin adoption and more people will acknowledge Bitcoin on the other hand the tenant only spend a few Bitcoin for a good purpose which means more adoption. If we want to Bitcoin to grow we should support anyone who wants to pay with Bitcoin or anyone who accepts Bitcoin as payment.
