While some people are financially stable and others are not, financial stability is dependent on some factors, of which financial management, as a factor, plays a vital role in being financially stable.
IMO, the answer to your question is an absolute "yes." Some side hustles just require a little time or a few hours and can be helpful, but if a person does not also have the skill of financial management, they can still face instability, and the side hustles may just seem not to be helping them. But, sincerely speaking, side hustles are not also improving financial stability for some people because of the economic stimulus.
The Bitcointalk forum gives individuals a lot of side hustle opportunity, as I have seen from what I have studied so far.
Some members get paid just to wear an avatar and contribute positively to the forum. With 3 hours spent in this forum on a daily basis, one should be able to create at least 3–4 meaningful comments on a thread or open a topic that could help others. This is also a side hustle because you don't have to keep 12 or 9 hours in the forum, which are the hours required in some permanent jobs.
At least one can be a bounty manager, signature manager, signature designer, ANN thread designer or manager, CM, GM, lender, paid texter, and paid reviewer. All this side hustle can support a person's financial situation when they are good at it.
My side hustle has helped me stabilize my financial state and not just dependant on one source of income.
