Although some people might think it’s a bit regrettable to sell Bitcoin at this time, for me personally, since a house is a primary need for me now, I consider this decision to be the right.
As far as the money being put to good use, there is nothing wrong with that; you have sold out to achieve something that you desire, which no one will blame you for. Congratulations on your new home.
The price of the house is actually at a good level; if that amount can get you that kind of house you showed in the picture, here in my country in a developed area, I don't think you can get land and raise it to roofing level with that amount, unless you are lucky enough to see someone selling off in distress.
