What have you got to invest? Most legitimate places will give 1-2% per annum in btc here so it might not be great for you...
I'd probably suggest, if you want somewhere safe to try binance who offer 0.73% a year with btc but higher rates on eth and tokens that CLAIM to follow the dollar. Link:

(if they post daily rewards then remember they'll go down and miners become unprofitible in around a year but you could experiment with it).
There's also defi which you could look up but it's very fresh and may not be safe (although I do have funds in there) you won't be able to hold btc in those contracts though and will have to convert it to eth, dai or many other coins.
You could invest time, either look at marketplaces to gather funds or look at creating something others would want or would want to advertise on. The age of freelancing has sort of made it so you don't have to conform to a tight schedule so if you had to take your mom to the hospital or something - you wouldn't be expected to work unless you'd given yourself that as a deadline although it's normally better to overestimate (1.5x your optimistic target).
Disclaimer: I have no link to the companies I mention and these are generally companies I'd trust with some funds, do your own research from here if you can as I don't want to decide who you trust.
