Hello anyone knows here what is the Maxx supply of Waves I thought it was 100m but cmc show supply is increasing..

As Midas111 said the supply is unlimited now, The change happened about 3 months ago. You can read in detail regarding inflation here. https://blog.wavesplatform.com/waves-community-driven-monetary-policy-e9018d35b911

It's true that coins are now generated for each blocks.
The monetary policy allow votes to decide how much.

But how did the last voting period ends? I have not found any results nor got any answer.

Where can I read about the result from the last voting period for changing Waves block reward size which has started on 9 December?

reward is maintained at the previous level 6 waves per block
