I have 0.1 BTC when 1 BTC price was 9k USD, so that means 0.1 BTC is around 1k USD. Right now 0.1 BTC is around 5k USD. So till date I dont think 0.1 BTC is like owning a mansion unless you live in some country where real estate is very cheap. I can own a mansion in my country if I have 1 BTC as of current price.
