Ive been thinking if it went into very high figures i could cash out 80-90% of bitcoin and buy a house outright with no mortgage. Is that even a good idea though? - basically 80% of networth in a house hmmm. On the other hand i dont want to have a mortgage and im fed up with renting due to landlords, letting agents and lack of control.
About landlords they are doing this because they also want money for their basic needs and for their family, it's your wish on how you want to spend your bitcoin on, but just make a wise enough decision which you will not regret later on.
