Exactly. Also I wonder what the fee for 1 input and 365 outputs (1 year) would be on noncustododial wallet. It would be better for Maliceprime to have weekly or monthly saving plan in a way this can be achievable.
Assuming that he will use a centralize exchange, there's no way OP can withdraw the bitcoin daily into his wallet because there's a fee related with the withdrawal & that's quite high as far as I'm concerned.
OP, if you are planning to buy for at least 5 years, I guess this worths. Otherwise, it doesn’t. You may eventually will find a good ROI but that's not going to be a handsome amount. I don’t know where do you live but $1/day saving for 5 years wouldn’t make a big amount I guess. Better try to purchase bitcoin now and invest some parts in altcoin when you get some good GEMS there.
