I still haven't read everything on the GitBook page, to make my experience more realistic. It's safe to assume the average user is not going to read anything, and jump right in.
Why read the manual now, when you can just read it later… once something goes wrong?

Why?
This transaction confirmed in about 2 hours. I know it's
dust, but I don't see any on-chain limitations against this. But if fees go up again in the future, $30 may not even be enough to cover it.
So even with $100 in BTC, the 260 sat is under the on-chain dust limit. And if it would reach the 294 sat limit, the dust is almost worthless for you to spend.
Suggestion: don't charge the service fee on small transactions.
As we posted earlier, there will be
no Service Fee for the first 6 months, so this issue is temporarily resolved.
We will continue our
deep research on
Dust Transactions.
Thanks to your idea, we will also consider introducing
fee-free exchanges for small amounts.
