If you had rented it out, you would have earned money from people as well as profits by selling rather than keeping it vacant with no passive income.
No, I won't rented my house because maintenance is very huge
than If I hold BTC in 10 years.I also lazy to collect the rent each month.
There you are making an assumption , that holding btc for 10 years will be extremely profitable.
You are confusing past performance with future profits, that usually ends badly.
Let say you sold that house ~1 year ago for $320000 US Dollars.
You converted that $320000 US Dollars to 5 Bitcoins.
Holding it for 1 year, your fiat value of those 5 bitcoins is only $85000.
So you lost access to $ 319915 of fiat value.
That is a very bad move.
But you are like ok, I can wait 10 years.
While you are waiting for BTC to grow to $1 million.
Scenario 1: Very Likely in less than 5 years
The US / Canada / Europe Governments all ban PoW mining and outlaw any trading of PoW coins.
Your bitcoins worth become inaccessible to you almost overnight as the price per coin plummets as all Corporate and Ultra rich investors received early warning from Political allies and cashed out. Leaving the smucks that think BTC can only go up, to get crushed, like a Tulip under a 800lb fat man.
Scenario 2:
A little paid attention to fact, is that anyone in these forums since the beginning have seen many well know users die in a 10 year time frame.
Their BTC lost, because they kept their private key secret from everyone.
Not everyone reading this post will be alive in 10 years, morbid but true.
Scenario 3:
Like many you purchased your BTC all at once and instead of testing sending a little, you just sent it all on the 1st try to an incorrect address and lost it forever.
Now is it possible you avoid all of those scenarios and cash out at $100000 per bitcoin,
sure,
it is a possibility not a guarantee. Which is why all crypto is a speculative investment.
By thinking BTC is guaranteed to increase in price in 10 years, you think it is a guaranteed reward, it is not.It is a gamble that can pay off big or wipe out your entire investment.
If you don't respect that , it will bite you, just like that guy Sam at FTX.
Guaranteed and Speculation are two different things.
