Hello,
sometimes I see coins on coinmarketcap which shows extreme gains,
but when I look at the exchanges, the price is much lower.
For example 6 $ on Coinmarketcap and 2 $ on an exchange.
How is that possible? Is this a bug or manipulation?
Maybe delay? or manipulation of exchanges? all possible. but be careful as sometimes there's a maintenance on going so the law of supply and demand there is different but the trade is still in working.
