Considering you have 2 houses, selling your abandoned house is okay.
However, if I were you, I won't use all the money to buy Bitcoin. I only use half for buying Bitcoin, while the rest for relatively safer investments such as gold or land. I think diversifying assets is always a better option because no guarantee for profits on Bitcoin, it is also a high-risk investment. Another consideration, sometimes we need urgent money, we can't rely on Bitcoin to sell at any time. Bitcoin is for a long-term holding, the price doesn't always increase, it may drop to a lower price in the next few months. We only can expect to sell Bitcoin in the next bullrun, unfortunately we don't know when the next bullrun really happens. It may be in 2024, 2025, or afterward.
