For example, if you run out of your emergency fund and you need more money, you can take help from the reserve fund.
You make little to no sense.
Why would anyone take from their emergency fund prior to taking from their reserve fund?
There should be an order and a priority, and if one has strong finances they may never need to even dip into their emergency fund for their whole life - 20-40 years or longer... if a person is getting close to dipping into their emergency fundx or if they have already done so, then there may be some signs of urgency, including that they have already exhausted any other backup funds that they might have and that they would use prior to dipping into their emergency fund.
Sure there are likely a lot of newbies who are not even used to having (or maintaining) and kind of emergency fund and/or back up funds, so likely their earliest of years of investing (presumptively into bitcoin), they are going to be getting used to how to build and maintain such backup funds and how to prioritize their usage, including figuring out how strong their financial status is or if they might need to start to curtail their spending in various ways if they are starting to get to a point of exhausting their reserve funds prior to even touching any emergency funds, which hopefully they will never have to touch...but yeah, sometimes actual emergencies happen (rather than emergencies that had come about merely due to sloppy cashflow management).
For example, I might have $5k and my total monthly income out of which my basic monthly needs will take $1k, so I can decide to set aside $1k as emergency funds and invest the balance $3k into Bitcoin month. This is being aggressive because the percentage of my income that is invested in Bitcoin is extremely high but that does not mean that my needs are suspended and I did not get up emergency funds.
This is a strange example.
In order to figure out your level of aggressiveness, we likely need to know more, including what are your monthly expenses and what is your income. do you already have other emergency funds and reserve funds or is that the total amount that you have in your bank? Are you just starting investing in bitcoin or have you already accumulated some? Do you have other investments? or are we talking about someone who is new to investing so only has bitcoin and cash?
