If you will ask me, I would suggest to not to sell all your properties but instead diversify it. We all know that crypto market is very volatile and we cannot predict what will happen in the next few years, but properties value arises each year but only depends to the properties you are talking about, having both things are good and good for your future.
It's not worth it to sell your property just to buy Bitcoin unless if you are rich and own many properties then I think it's okay. It is much better if the money that will be use to buy or invest in Bitcoin came from salary like 1/3 of the salary or depends on what you do and it's not much hassle.
