Yes there is: mining
At $0.15/KWh for example, an S19 series ASIC will automatically convert ~$330 per month into KYCfree Bitcoin. Its the best way to DCA.

Interesting. Maybe I should start listening to pod256.
S19 breaks even at $.15 /kw ?
No, I just used $0.15/KWh as an example electricity cost, so that I could calculate the monthly operating cost, assuming the asic consumes 3KW.
Break even cost depends on Bitcoin price and network difficulty, so that answer changes all the time. The point I was trying to make, is that ASICs perform DCA at whatever your electric rate is.
