According to the fragment of the Arbitrage USD "10" overview, (please click the link below) it seems to be a great arbitrage occasion between vcxUSD and a handful of other exchanges (Bitfinex, bitstamp, btce, coinbase, hitbtc, Kraken, lake, okcoin):

Does anybody know if vcxUSD does support USDT (Tether)? So that we can transfer USDT between vcxUSD and Bitfinex (bitstamp, btce, coinbase, hitbtc, Kraken, lake, okcoin)?

Or does the fact that an arbitrage win between this exchanges are so high indicate that USDT is not supported between this exchanges? As if it would be possible, the arbitrage win would be much lower?

Why seems the arbitrage win potential between the mentioned exchanges so high? Is there any problem to put it in the praxis? What is the hook?

Thank you for clearification. Would very appreciate your answers.

Hi,
first we have to ensure that we understand why the price we are seeing is that low and confirm that it is not just an error.

Here is Bid orders in the orderbook

And here is Ask orders.

This orderbooks you can find on the Depth tab.

On the screen shots you can see highlighted volume in the Sum column.
For the Ask orders it is very obvious that although the price in the top most orders is close to the 355.
The volume of those orders are way too minuscule that in order to actually sell 10 BTC you have to cover all orders till the highlighted row.
And the price you actually will get while selling your 10 BTC will be not the 355 but an average between all orders which you fulfill including that with the one which is highlighted with the price 10 USD/BTC. But of course you will fulfill it only partially to add the difference from all preceding fulfilled orders which will sum up to 3.1btc. Thus the difference will be 12.8 - 3.1 = 9.7btc
So if you sell all 10BTC the most part of your sell order 9.7 will be sold at the 10 USD/BTC price.

The same logic can be applied to the Ask side.

As to your question from the screenshot of the Ask side we can confirm that there is not error in data and calculation of the price in the arbitrage chart on you screenshot.

And thus we can deduct that this price is what it is in the order book.
In general this situation can be characterized as low liquidity. Why some exchanges has different liquidity this is very specific question and there can be a lot of different answers.
Usually low liquidity is caused by difficulties with deposit/withdrawal of fiat currencies. But the causes are not limited to just this.
