I have been playing splinterlands game for quite some time and tried to reinvest whatever I am earning. But the problem with small players is that they cannot earn as well progress well because of investment constraint.
As you can see though I have good cards but because of the Collection Power I could not advance to the next level even though my rating is more. So my collection power is at 15200 i.e. Silver 111 and my Rating is at Silver 1. That's why collection power is important to go to the next level.
