Of course each claim should go below 1 mrai! This is the only way that the value will go up on each coin, as it is directly correlated with how much work it takes to claim. This is the equivalent of the difficulty going up on a proof of work coin. It means more people are claiming, thus more are interested. I see this as nothing but good.
But if you look on the exchange people do not want to buy at 400 sats,we really to put an effort mrai on any exchange so we can push the value up,some people choose to wait and see and just hold their mrai because they know that it will be profitable doing so,I hope a big whale here can pay the fee for nova and yobit.
What I noticed is, there are users who uses captcha solving services for dead cheap rate. That's why you get this high difficulty. The real people who claim here is very few.
