Depends on the usefulness of the service, and how quickly 10 units of the service would be used.
If it's like a really good coding bot, probably. If it's just a video slot machine with a button, no.

it's not a slot machine 😉 - I'm coding a slot machine for fun, but that's free,...
the service would almost never reach 10 uses for one person, and the "tipjar" would just pop up now and then.
thx for the input
