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.
For you it may sound like a bad idea because of so many reasons which you think it is not good for you to spend such a large amount of Bitcoin to house rent but this person he knows the reason why he decided to spent bitcoin for rent best to him. I don't think spending bitcoin on house rent is wrong, bitcoin is money that can be spent, it is not just for hodling .
I know this is the period of hodling Bitcoin against the coming bull market but if one still have much of it to spend it, then it is not a bad idea to spend bitcoin. In some countries bitcoin have been accepted as cash which people can spend it just the way fiat is spent. Bitcoin is money and everyone will decide what to spend his/her money on. Since bitcoin is money, you know money is meant to be spent, this is one of the purpose of having money.
The use of BTC for payments and transactions is not a new thing. Businesses in most countries accept BTC payments and individuals may request their bosses to pay them their salary in BTC.
I am not just exaggerating, I have read countless of stories here on how individuals got to accept BTC payments for their business and am very sure real estate business ranks among businesses that can and should allow BTC payments since it may incur less fees than what the bank would offer.
It depends on if the house owner also decides to accept the rent payment in BTC and also if it is a legal tender or it is not banned in total by the government in that country or region. So it would be necessary to ask first before concluding on the payment option of cryptocurrency.
More than just waiting to trade and make profits from BTC investments mostly as new events are unfolding like the ETF just being approved and the halving to happen, is the choice to either HoDL, spend, diversify, convert to other trading pairs or simply just accumulate. Everyone has a choice of right to do as they deem fit with their crypto holdings.
