The reality is, merits are not for longest post you can construct, rather its for ideas that are useful to readers especially to those who already know what cryptos is all about and just looking for additional information.
That reality is as per your perception. Different members have their own criteria while giving merits. Some might be giving merits to the posts they just agree to . Some may have asked an urgent query and if some member helped them with the response in very less time, they might consider the activeness while awarding merit.
Most of the members here already have all the basic information about bitcoins. Those who have no idea, join as a newbie after finding this forum through search engines. Even if thyer find your ideas useful, they have no merit to give to you.
