The average housing price in Canada is $659,395, selling Bitcoin using DCA strategy when you don't have enough coins to buy house, is not a wise decision for me.

I suggest you're need to wait until the price surge really high, let's say you think $150K CAD is big, you can sell some portion and hold the rest. People are expecting the highest Bitcoin price in this year halving event will happen in the next year, so you can sell some at the top.
