Its not just an unpopular opinion its downright insanity i am just selling a property i bought at the time i was a bitcoiner but i wanted a base in the country so i aet it up as a rental. At the time it was worth around 300 bitcoins now it is worth 5. I worked it all out i could have had around 25 million and none of the hassle. After all the renovation and maintanence costs and fiat value melting like a giant iceberg instead i made a small loss. Lesson learned will never invest in property again however land with water, energy and resources ia another matter
