can  anyone answer  to this

"
i recently have had some doubts about the current supply of 14,383,080,442 XVG. Not that it is too much, but i think we are to close to the maximum supply. We mined in last 5 month 1 billion coins, if this will continue, the mining will end in 2 years from now. Where is then the reason to mine that coin and invest computing power to it? The only reward will then be the transaction fee? Where does this lead? Can somebody answer this questions? I have a big bunch and will hold it anyway, but i fear the network will get slower then or even get stuck? To 16,555,000,000 XVG is only to billion left. If verge gets now more popular, the mining mighjt get even faster. Where and when does the difficulty adjust and how does it ensure that miners will not leave the network? Is there an overview of expected behavior of the network for different scenarios?



thanks
