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.
If a person invests 80% or the entire amount of discretionary income, then we can call them aggressive investors. If they invest through the DCA method, we can still call them aggressive investors. Because they are investing the entire amount of their discretionary income, which cannot be called a normal investment at all. Buying only through DIP or buying outside the DCA method is not something that will make them aggressive investors.
investing 80% or your entire discretionary income in bitcoin may look to you as aggressive investing, but to me its not, because I see it as a wrong investing and not being aggressive. Remember from your discretionary income you will build your emergency fund and backup fund so if you are investing 80% or your entire discretionary income in bitcoin then how much do you intend to allocate to your emergency fund and backup fund? Emergency fund and backup fund are very essential for you to have as an investor, so that when emergencies arises there will be funds to handle those emergencies instead of dipping hand into your bitcoin investment. So in this case I will advise you invest 50% of your discretionary income in bitcoin and then allocate 30% to your emergency fund and then allocate 20% to your back up fund so that the equation will be balance. Because Even if you are investing 50% of your discretionary income you are also investing aggressively, so why do you want to endanger your bitcoin investment by investing 80% or your entire discretionary income without looking out for your emergency fund and backup fund that are very essential for an investor to build to enable the investor run a smooth bitcoin investment.
