Maybe you do saw the circulating supply? Total supply and circulating supply do really differ. Ive read on whitepaper too they do have 800+ M supply coins which we can really presume those listed are circulating.I haven't checked yet as of now and maybe you do have the right observation among the supply of coins. Going back 60 to 80% just too big and I would say you would turn out to be profitable and this is why we do see the price of KICK decreased because those people who poses the coins first are now taking profits.
The supply of the coin changed when the hard cap changed and dropped almost to half do probably the supply you are seeing on coinmarketcap is the accurate one , A lot of numbers changed when the hard cap changed you can ask about it on telegram
Thats explains the difference.. many ico's do this. Unsold tokens get burned or in some cases distributed for free to participants. happened to me once. Lucky ico's.
