Don't invest in either bitcoin or stocks.

If you don't have a emergency savings account I fully agree with itamarst below and invest in a emergency savings account.

If you already have a emergency savings account I personally would use it to either:

1) Invest in myself (e.g. materials for self study, like a Pluralsight account)

2) Invest in goods which improve my quality of life (e.g. a new development box, kitchen peripherals, whatever), or:

3) Invest in bricks (e.g. my house)
