I think you've got the answer to your own question.
it's different when compare it with bitcoin
Don't just look at the growth of bitcoin without taking into account the risks it brings. Your home doesn't increase in value, but at least it's safe for you and real estate is considered the safest asset. For bitcoin, it might give you 3 other houses but could make you homeless in the future.
Don't and absolutely must not do that, invest with money that can be lost and make sure it doesn't affect your family's life.
Bitcoin investment still not guarantees secured profits because of its high volatility, so never compromise your property just because you are tempted on the future profits of bitcoin. Your property will always be your own possession no matter what but with bitcoin, you will never hold an assurance that it wont lost its value and you sell it eventually at a cheaper price. You can always invest in bitcoin if you want, but only an amount that you can afford to lose, and selling your house will never be reasonable and definitely an illogical thing to do.
Maybe selling a house in which a family resides is illogical. Here the house OP have planned to sell is an additional house that is not in use. Selling the house could help him invest into cryptocurrencies. One thing, he need to prepare his mind to accept the positive and negative market move. Also, he should have the patience to experience the best out of the investment. If his plan was to sell the house, buy bitcoin and the next day sell bitcoin and buy two house. This won't happen.
I say something, if you have a house to stay and live in and if you have another house that you don't use and that you don't want to rent, I would sell and buy the bitcoin because I know that this investment is going to become very large, the bitcoin is at 16 thousand dollars, it could be that it reaches almost 100 thousand dollars and the person earns a lot of money and can buy a better house than the one he sold and a car and everything.
people sometimes do not see the fruit that can be obtained from a good investment, some buy cattle, others invest in the stock market, others put their money in investments that what they do is steal money, but the one who invests in bitcoin is a person who will never lose money.
We all here know that investing in bitcoin can bring huge returns but no one here can 100% guarantee it will happen its all just guessing and hoping it does real.
Of course OP could sell that house for investment but what people want him to understand is that the investment is risky and the higher the return the higher the risk and bitcoin is not a get-rich-quick, nor does it guarantee 100% returns, there are still risks with bitcoin.
If you dare to affirm that bitcoin will be 100% profitable in the future, then I think you can also sell all your assets to invest in bitcoin, not just idle assets.
