All this shouldn’t be complicated. If you are interested in bitcoin, all you have to do get yourself to be familiar with the basic concept. Then learn how to make good use of custodial (buying) and your noncustodial (for storing ).
Then you can start with any amount you can afford at the moment, that won’t affect your emergency funds and backup funds allocation. With enough back up funds those that always have the urges to buy the dip , don’t need to wait for the dip before they start accumulating. They can literally save some backup funds to buy the dip .
You don’t have to be Rigid towards your bitcoin investment. As an investor you have to flexible in order to adopt to any situation or condition. Sometimes your inflow might reduce and you won’t have to reduce your accumulation amount what you will just have to do is to make some adjustments in your spending to adopt .
What basic concept of Bitcoin does a beginner have to learn first that is more important than figuring out his discretionary income and kickstarting his accumulation journey immediately? From the beginning to the end of your post is vague.
Obviously you don’t know that emergency funds is a type of backup fund. You seem to be separating the two. So if you’re saying folks should save some “backup funds” to buy dip(that may or may not come). You’re indirectly encouraging them to buy dips with emergency fund.
Maybe you wanted to say reserve fund? It is also a type of backup fund; but flexible unlike emergency fund. You can buy dips with it and also use it to take care of emergencies before tapping from your real emergency savings if it is not enough.
