i don' t understood so much...anyway the price changing on coinmarketcap is false or what? 
no it is not wrong, it is just a calculated and weighted average value of all tradad dimecoins within the last 24 hours on all exchanges in all markets
in theory, yes, but there's really nobody paying 0.000058$ for one dimecoin, so that's a glitch or just a blatant lie. CMC just inst reliable when it comes to superlow volume coins
