Question: Is it OK to ask for donations?

Just a quick question: How does the Steemit community feel about articles that include non-Steem donation requests, say Bitcoin?

I ask because I'd like to use Steemit as a publication platform for thoughtful, longer-form content, and I find the Steemit payout algorithms somewhat confusing.

Specifically, how does the timeout work? Can I earn Steem at a much later date, say a year after posting? If not, then I'd like to include donation addresses in my articles so that future readers can donate directly if they find my content valuable.

But before I start including donation addresses, I thought it prudent to ask what the social norms are in this area. I'm new here. Thank you in advance for your advice! 😅🙏
