Well it is practically impossible for an investor to be investing daily unless the investor earns daily and even if he does, I don't think it will be convenient with the Investor and I think this can only work ideally. Additionally, investing daily, weekly or monthly with discretionary is not an aggressive investment perhaps you should use the word intermittent investment because aggressive investment is when an investor used a good amount of money that is beyond their normal weekly or monthly investment money (DCA money) to invest in Bitcoin and this is the reason why I said it can not be possible to do that because aggressive investment amount is always bigger than DCA amount.
You just said it's impossible then countered yourself by saying expect the investor earns daily, mate it's not impossible to invest on a daily basis but the time frame the investor can keep up with it matters, it's a matter of how long, not how possible, for instance their was a point when microstrategy was buying on a daily basis then along the line the switched their interval of accumulating when they couldn't keep up with it. It all depends on the time frame at which the investor generates their discretionary, a salary earner who earns weekly is bound to invest on a weekly basis, one who earns monthly should invest on a monthly basis, a business person who get better profits on a daily basis can decide to buy in a daily basis for as long as they can keep up, that's just it mate.
