"Voting bots making holding Steem power and delegating to a bot one of the best opportunities for investors to earn cryptocurrency just by holding without touching the principle which is very good for the Steem price trending up."
You got it wrong here my friend. In short term yes, "investors" (aka, quick money seekers) will earn more than they have put in. In the long term this only hurts the platform as rewards are not going to people that build up value on this platform. With voting bots al the value flows to the bigger stake holders.
Before voting bots, the primary compliant was circle voting where those with the most stake voted each other up. No matter what we do here, the value will flow back to the bigger stake holders one way or another. Voting bots make that flow transparent while circle voting was often more difficult to see and participate in.
It is different.
So your primary complaint with voting circle are:
To the first point, of course its more difficult to participate in that is why its a voting circle. But atleast with voting circles it doesn't cost you anythng to participate in, while with voting bots ROI is not stable and can be negative even. (I don't know if there is a profitability in this). The second point is that in voting circles there is more chance of it going to relative good posts, as opposed to now most of the votes go to shit posts that fill up trending. I joined before voting bots became big, and although I remember I was frustrated seeing the same people in trending over and over again, I still think there were some good posts in between. Now I barely look in trending.
Point 2. "More difficult to see" You imply here that because everything is open with voting bots it is better because? We can stop the votes more? I see some vote bot owners putting up whitelists, but how efficient are they really and how will they be able to manage the list of millions of people join the platform.
I agree with you that either are bad. But in my opinion when we don't have voting bots, atleast the big stake holders will need to put extra effort in voting and choosing where there votes go. Like to quality content creator Jerry for example.
