Dca help

Hi guys

I am 27 rn married

I am stacking btc from last 3 months

I am planning on doing 3k aud monthly dca into btc for 1 year but also my wife wants us to buy a home. If i put my dca than i have not much savings to show to get a loan for the land entitled for building the house.

So its either sav for a year and get a home loan or put as much as i can ( around 600-700aud) weekly in btc for a year. I can take this risk as i know this is the last chance before 2028 halvings to accumulate as much btc as i can.

Help is much appreciated

Also i pay all the bills including the rent and can happily dca the amount as my wife saves for the house and land in future.
