I think HQ got it under control. Last year you got 5 lisk pr block mined and it got lowered to 4 lisk pr block in December last year and then it will be lowered to 3 lisk around December this year and so forth until its only 1 lisk pr block. I'm not sure if my numbers and dates are correct.๐ And not to criticise but you could have found all the information on the lisk website. ๐ Hope this helps you out.

This is from the lisk website The block reward linearly decreases over the lifetime of the network, providing significant incentive to actively participate as an active delegate. The reward will decrease every 3.000.000 blocks from the initial reward block
