Why different exchange markets have different prices

[Glydel1999]

It is because in different market there has different admins and different number of users, and in every crypto market there has a different prices of taxes that they paid ,
thats why there have a different prices in the exchange market.

Hi,

I noticed that there are some huge differences on exchanges for E-coin (ECN) . For example : it's worth 90 $ on Yobit, 160$ on coin exchange and 7 $ on c-cex. I get it that there might be slight differences, but this huge ?!?! 

Also, did any of you guys trade on any of those 3 exchanges? which would be the safest choice ?

say.. BTC is $1070(sell) on poloniex and $1135(sell) on cex.io why would anyone sell his bitcoin on poloniex at the moment and not transfer them to cex and sell them in there?
The reversed is still true, why would anyone buy on cex since the bitcoin is way cheaper on other markets?

this way and used by large players, called it arbitrage, a simple investor is not profitable to do this you need to have a lot of money on each exchange. And with the arbitrage traded mostly robots! Here's the link for comparing prices: http://www.arbitrage.expert/

Because the volume of cryptocurrency market still small compare others market like stock or forex, and that why exchange have different price. And also the demand in each exchange also different, small volume also will become the price less in liquidity.

The fact that withdrawal fees, late deposit on requested exchange when the price stabilises and the associated trading fees are some factors hindering me from arbitrage trading. Maybe I'll try it out with little cash
