Well I've officially found the house that I want... Now to just get bitcoins to the $250K ea I need to buy it...
$250k in the next 10 years is doable given the exponential growth that bitcoin will experience, but of course, aiming for anywhere near $10k to 100k is more on sight.
You should focus in trying to buy as much BTC as possible while it's only 4 figures, then you will need less BTC to buy your house.
In any case, you should never sell 100% of your BTC.
Wise advice, waiting for bitcoin reach $250,000? It may take 25 years, too far away and seems impossible for now.
Better to buy bitcoin at cheaper price (whenever dip occurs) and wait it rise tripled then cash out to buy a house that you want.
However, you need to start a business to get more money instead of just rely on bitcoin.
