I have set up my node and I have bought some BLP on cryptopia to vote for me. But I found the block that I forged is proportional to the votes, that means the reward is proportional to the BLP I have, right?
Yes, but you cannot vote from the exchange wallet (cryptopia). To vote for your delegate, you'll need to move your BPL tokens to a desktop wallet and vote from there.
I hope this helps!
