I know about those people, and sadly, that's just how things are.
Some of them use bots, some of them just ask others for upvotes, while others receive a lot of rewards for the simple fact that they have a lot of SP, and people upvote their articles hoping to get something in return as well, which usually doesn't happen.
It's how it is, and there's nothing we can do about it. Those who have a lot of money will almost always make more.
Focusing on getting better at writing is what ultimately matters. If this system stops working for those people, you'll at least have the skills needed to write great content, and that's what people will be interested in.
If Steemit goes down completely in the future, using another platform and knowing how to write well enough to get some attention fairly fast is also gonna be useful, especially if the systems that work here for some people won't work on those other platforms.
Mastering a skills is a lot better in the long run than making a quick buck now.
Thank you for reading and also for the nice words! :)
