If we lived in a perfect world, we would all just stop buying their stones and they would be forced to find another business model. But because people keep buying spirit stones, everyone is getting swindled by this system. The quality of the translations here does not warrant such a cost, especially the quality of the stories. As someone above already stated, its cheaper to buy physical books and they are usually of a higher quality both in storytelling and language.
The best thing you can do is just suck it up and read less. If everyone does that, then we might see some changes. But never bend and buy stones, thats the last thing you would want to do. When you buy stones, you are not only harming yourself, but also others.
Buying extra chapters only increases the amount of money you will pay in the future, because the stones will run out and you would want to read, so you wouldn't wait for weeks for a new chapter, you will just pay more to keep reading. That's why if you care about reading, you shouldn't buy stones.
If all you want is a short burst of extra chapters and then weeks of no chapters, then this system is for you. Otherwise, its a rip off. And the people of lower IQ fall into this trap and buy chapters, then they are forced to pay more because they can't wait due to their lower intelligence. Deferred gratification is something people of above average intelligence understand, and Qidian is exploiting young people and people of lower intelligence to buy in to this rollercoster of spirit stones. You can't stop paying, or you can't read!!!
