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.
