One Bitcoin one house can happen pretty fast, at least in the countries the real estate bubble is about to pop!
So it's not unrealistic and mostly will depend on where you live.
If the prediction of the first investor of snapchat that bitcoin price will be $500k in 2030 happen, then we can buy a house with even lower than 1 bitcoin. Deflationary features plus exponential adoption can make the prediction happen.
You're right and I will not try to deny that. Neither me or any "expert" knows what's going to happen in the far future with Bitcoin and all other crypto currencies.
And yes Bitcoin has an enourmos upside potential.21 million tokens is nothing compared to ~7 billion people on this planet.If mass adoption should happen, 6 digits may be a goal in a few decades.But this is pure wild guessing.
And to support your argument with the snap chat investor. He isn't the only one saying that Bitcoin could reach 6 figures.There are people who think it BTC could be even worth more than a million USD. But I'm not one of the guys who likes to think so much into the future. Bitcoin i still very new technolgoy and a majority of the world population still have no clue how it works. Thefore I prefer to think in small steps. Bitcoin right now is like internet 1992-1995 imo. Patience is needed.
