i'm checked at coinmarketcap is not found longcoin, i'm read at first page not found total supply and circulation supply longcoin, can you tell me about it?
As far as I can remember the developer talking about the maximum number of coins mentioned the figure of 40 billion through 20 years of mining, now in circulation after two years from the beginning of mining is about 3 billion coins, but it is known if the community decides after the 500,000 block's will be having, so then not every miner will be able to survive until the time of extraction of 40 billion coins

As for the information on CoinGecko, now there is a paid listing and the developer does not have the funds for this, and the community is not yet so large that it would raise funds for this.
