The supply of bitcoin will increase but not more than the usual. New block releases into the network. Try to familiarized into mining and you'll know new blocks released new bitcoins.
Why would you want the supply to increase?
There is a misunderstanding: bitcoin supply increases every day by mining.
What you can't increase is the speed of production.
So, as anyone knows, in any moment there will be a fixed amount of bitcoin in circulation
circulating supply is increasing. But it won't go Beyond 21 million. even if you mine for a millenia.
