Money is a measure of exchange. It is a measure of usefulness of good and servises. De facto Merit has become internal money of this forum. You make useful post - you get merit. This is how money work. After that you change those merit+your next labor (doing posts for signature bounty campaigns) for other money - bitcoin, usd, ruble, other currencies. This is forum is about cryptocurrencies. Everyone here want to have opportunity to change their tokens (different cryptocurrencies) for other tokens (+fiat) in a free way. Everyone feel this is fair.
I'm not going to argue with owners of this forum about their rules. Because this is their forum, their project.

But, I have only one question to you, owners.

Why don't you give free access to buy and sell Merit for users of this forum?
