Coin market cap has routinely listed an incorrect value for our supply, we have contacted them many times and they fixed it, but then reverted back to 2 million after some time frame. We have continuously contacted them to resolve this issue, providing the API in which the lice value can be accessed directly : http://www.expanse.tech/explorer/api/accountsupply however they did not update it to a current value until just a few days ago.
