So, i was solving captchas in the morning and gathered around 4000 mrai said that pink box, but when i checked later the same pink box says that my actual reward is just 2200 mrai. My question is why i lost mrai if i don't claim for a while?
It is very simple, your reward is an outcome of equation which is number of your claims divided by total coin reward and number of claims done by other users. When you stop claiming and other peoples claim count is growing, your reward decreases. It is all the same for all people taking part in this.
