I was about to sell some BTG and opened Coinmarketcap and checked the price. I was amused with the price differs at different exchange.
Currently its about 0.0028 btc per btg at 99% of the exchanges, but at Yobit its at 0.0014btc per BTG. why is the big difference in Yobit price?
And can we simply buy at yobit and move those coins to another exchange like hitbtc and sell at double price?
It's because of wallet sync problems from Yobit side. If you click on withdraw, you will get "Wallet status: Maintenance".
When you stop an arbitrage with big difference, in 99% of cases there is sync wallet problem from one side or the other and in reality there isn't arbitrage at all.
