Even though you keep the house it will be a waste. And if you say, you want to renovate it, you will spend a lot of cash to renovate it and probably you don't have enough money to do that. But issue is technical. If it was me, I would have rented it out and use the money from the rent to buy Bitcoin, for renting it, the land and building is still your own,. And you can be making money from the rent every year and also using it to buy Bitcoin Everytime the tenants paid their rents.
There are several ways that the OP can do?
First: Sell the house with the assumption because it is not used, then build a bitcoin investment, even though the investment made will be faced with risk.
Second: Rent out the house and use the rent to invest in bitcoin.
These two patterns look good to practice, but the first option is much more innovative in terms of utilization, because if you calculate the use of rent for the house, it is not much more effective than investment. Technological developments in the utilization of money must be utilized to greater advantage, this will not be achieved if only pattern number two is used.
But that is you personal decision, either you rent it to make money from the both sides or you sell it and use all the money to invest on Bitcoin. I prefer renting. But the final decision is yours
In the end, whatever decision the OP takes is the path of choice, this cannot be influenced by anyone, but I think investing in Bitcoin is the right choice for now.
