I thought I was the only one with problems understanding eos haha. For a while I didn't know the congestion was happening all over and I was trying to buy more eos in order to stake to cpu but no luck. I still don't know how to do it. I have a mobile wallet supports eos, maybe it could be possible to exchange from a different crypto source to eos then transfer that to my scatter... But similar to what you were saying, maybe my eos adventure ends here
