I've decided to quit smoking today.

I'll use all the money I save from not smoking to buy BTC.

I smoke one pack a day, 15 yuan, roughly 2U.

If I can resist today, I'll buy 2U worth of BTC tomorrow.

I plan to keep this up until I'm 60.

I'll quit smoking and continue my regular investments without interruption.

When I look back on my 60th birthday—

how much money would all those cigarettes I didn't smoke have earned me? $BTC
