It is a bet that can certainly work out (borrow to purchase lump sum vs DCA'ing with your own cash flow), specially if applied during a bear market.

However, there is a BIG downside here with the borrowing service... You are not really purchasing bitcoin because you don't have custody during the investment period - only at the end. Unfortunately, many unforeseen bad things could happen during the investment period and you could get rekt. When DCA'ing to purchase bitcoin and putting it into your own non-custodial wallet, it is truly yours.

Bitcoin is remarkably simple: just DCA with your own free cash flow over time and you should be fine 😊
