I want to know if i can mine in mobile wallet or if it's just pc wallet ?
If Yes it is always 69% of interrest by year ?
To be able to mine/stake OK, you need to full blockchain on your device. Right now no mobile wallets allows you to stake your coins. If you are looking to stake with a very low electricity fee, you can acquire a Raspberry Pi or a PINE64 and install ROKOS on it. This will allow you to stake at about 12W per hour if I remember well.
The 69% is over been a while. We had an halving in January from 20% to 10%. The current yearly % is updated on the first page of our thread.
ho..what is rokos ? full os or just apk ?
