Backup funds and emergency funds are not invested. So there's no point claiming you are diversifying your money by investing your backup funds or emergency funds in shitcoins which has a very high risk of loosing entire money. If anything happens to the back up funds there, your bitcoin would be vulnerable and you can either panic sell or possibly sell at loss in order to sort other life threatening circumstances. Shitcoins is not an option, leave your backup funds in a very accessible place where you can have make use of it anytime the need arises in order to hold your bitcoin for a long period of time.
Why should someone's reserve funds be a problem whose purpose is to have them for emergencies so that the funds are only stored so that their value does not disappear which in my opinion is more suitable to be put into gold because gold is also easy to cash in at this time when someone needs funds suddenly. As for the routine funds used to buy Bitcoin, I think it does not need to be disturbed and changed in nominal value because when someone is able to buy routinely with a nominal that is always consistent in the same amount, it will also have a pretty good effect on him in terms of increasing the number of Bitcoins that he considers as a future investment.
Investment your emergency funds looks a bit new to me, ordinarily i was thinking it was cash reserve you can fall back on hence there is real emergency, but investing in gold that is still prone to heavy market instability shouldn't be seen as emergency funds, in my own view, if it gets to the point you would have to put your emergency funds in gold reserve as an investment, why not just empty everything into your bitcoin investment at once since it's already looking like the emergency funds can be invested.
