choosing both of them in my opinion is the right choice so you will get 2 income and I did that until now, because investment in crypto doesn't require much time
Ideally doing both is a good idea as investing in crypto for the long term will help as now market is still at 4k so investing even now for next couple of years would give you a great multiple times returns and in the same time continue focusing on your business and grow it . This will yield you profits in future and in coming time from both of the things.
