Hey @abh12345.

1. It's true that you could lose money using the upvote bots. In fact, it's easier to lose money than make money using upvote bots particulary for those just starting out. That's why it's important to learn the system well first before trying this. The $ signs in the posts make it confusing because they don't actually represent the actual dollar value. But it is possible to mak a profit. I invested $700 and I'm now up to around $900. Granted some of that is from capital gains. But yes, you can make a profit, although modest, using upvote bots.

2. I get your point. Delegators to the bots are guaranteed a profit. Those with money make more money. That's not too bad because those with a lot of SP did invest time, money, or effort to accumulate that much. It's only fair for them to have a return.

3. While the reward pool indeed is finite, there's enough of it for everybody.

4. I do have some issue with how the earnings are presented on the posts. It's very misleading. I've been on steemit for more than a month and there's still a lot of things I'm just beginning to grasp.

Nice to meet you!
