Just to recap the facts... the home value was ~$400,000 and the OP traded it for 648 BTC
At the current pricing the OP now has ~$117,000 in BTC
but property is stable ,if we kept the house he would have minimal predictible gains
with the volatility those btc could be worth 2-3 million usd in a few yrs
thats the differnce

The upside is much bigger for Bitcoin and you have a legal risk of owning a property and many costs associated with it. Bitcoin is very risky and more volatile.
