Generally, when a question is about an advanced issue - I'd expect the OP to be sophisticated enough to find the answer through research, and not through passively querying a Q&A forum.
Essentially, advanced questions should come in the form "I researched this, read that, and cannot understand this point - please help".
Specifically to the question, which I voted to close as off-topic - I'd expect a person considering purchasing a seat on an exchange be fully capable of providing at least a basic list of pro/con considerations, and how they apply to him. The specific question clearly shows that the OP doesn't even know what having a seat even means, let alone be able to decide or even consider if it is to his benefit to own one.
I'm sure that the last sentence of the question (essentially a question "what does owning a seat mean?") would have merit on its own on this forum. But when added to a larger question "Whether I should have one?" it only shows that the OP is, well, clueless. And answering such a question will not provide any meaningful benefit neither to the OP nor the others.
I also downvoted the question, as I downvote many questions of that specific OP, since it is evident that he applied zero effort to understanding the issue on his own. Many of his questions (not all though, but many) look as if he thought of something - and immediately ran to the forum to ask about it, without any effort whatsoever to understand what he's asking and trying to find an answer (for many of the questions - that would be a simple Google query).
While we want our answers to appear on Google, I believe our answers shouldn't come instead of Google.
