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
Not only in theory: please have a look at coinexchange: https://www.coinexchange.io/market/DIME/BTC. Even if it makes no sense, people bought Dimecoin for $3722.57 within the last 24 hours at that high price. To buy a lot cheap, everyone should buy here: https://www.cryptopia.co.nz/Exchange?market=DIME_LTC
I have no idea honestly where you see any buy orders at that price, all i see is the absolute bottom where very small orders got filled :/
Sorry, my mistake: $3722.57 is the 24 hours volume over all exchanges and markets. At yobit and coinexchange we had just small amounts within the last days.
