SEPA seems to have no problem moving sub-euro amounts. I am not an entrepreneur, but I did send single euro amounts to my friends. Is it more difficult in USA?
I got interested in that after your comment, and apparently there are two main reasons for that.
1. Oxygen is being produced in stars by so-called CNO cycle [0], which is how stars heavier than our sun mostly do their fusion. More intriguing question is why there's more oxygen than carbon or nitrogen (which, as implied by the name of the process, are also created), but that's a different topic.
2. Additionally, oxygen-16 is a particularly stable isotope, as its nucleus has “doubly magic” [1] amount of constituents, so it doesn't get destroyed in other processes.

That's absolutely common practice in places where you can accrue PTO without limits. People rest with compensation they earned and then leave re-energized. And that's a good thing.
Am Russian, am vaccinated with Sputnik V, would do it again. Yes, the study was rushed and details were missing, but, eventually, all things got in order.
And it's a real working vaccine, effects of which I see basically every day on my friends.
