This is actually what I would like to explain in my next post. But I will not leave you without some answers.
The fastest way to earn some sats is to unlock a coin, every 2 unlock you will get a bunch of sats. So the fastest you unlock the fastest you get the sats. As you can see there is a map above, once you unlocked you can actually open a new world... and do the same there.. Of course the first time it take some time but I've found way to do it very quickly. In 1 day I do now more than 1K sats, but the issue is I can only transfer 500 / day :-) It doesn't require to be online all the time ... You need to unlock as much as you can and then sell your portfolio. Every 30 minutes you can sell your portfolio. SO you can start again and it's always a little more faster. Also you need the chests so that you can collect all the coinparts it will really boost and make it even faster...
