If one can save bigger amount for emergencies in 9 months, he should just concentrate on the investment for some times until the emergency funds is low then he can continue saving for emergencies, like after removing the monthly expenses from the monthly salaries hes receiving then he should just put the rest of them into Bitcoin.
Firstly, congrats

How much have you been able to add since OP? Nrw Year bonus I hope

This is me, my Bitcoin is my savings which means only to be used in emergency or in retirement, I hope the retirement option kicks in if BTC is 1 million before I actually retire in about 25 years lol
My advice is to have no expectation. You just started so keep building for a whole 4/5 years (1 cycle). Bitcoin still too unpredictable to rely on it but I'm glad you already understand this is a longterm thing!
