How many coin to stakes about once a week and what's the percentage?
Payments are monthly, non weekly. Percentage is about 8% per month, 10% per year.
From their whitepaper (
https://www.rebellious.io/rebellious-whitepaper/):
"In order to participate in the Proof-of-Stake system, you will need to keep your REBL tokens in your wallet
for a period of 10 days. Once 10 days has passed, your REBL tokens will activate and start earning you
interest for every further day you keep them in your wallet.
This interest will continue to accumulate up to a maximum of 30 days, by which time you will need to claim
it through your wallet. If you do not claim your interest, your tokens will not generate any further interest.
Once claimed, the 30 days resets and your tokens start earning for you again.
If claimed regularly, the rate of interest paid on our REBL tokens is equivalent to roughly 10% per year."
Also new wallet with selectable gas slider and time-to-next-collect counter is coming.
