Buying Bitcoin every month for 1 year

I stumbled across u/jamespunk monthly posts about a year ago, right when I started DCA into sp500 and index etfs. I thought bitcoin DCA was such a great idea that I attempted to recreate u/jamespunk google sheets, starting with $100/month and recently boosting it to $500/month. See graphs attached. Although I'm down bad rn I'll be hodling and stacking for 4 years minimum. Looking forward to what the future holds!

u/jamespunk thanks for the inspiration and imitation is the sincerest form of flattery!
