So I decided last week and have found it to be a case "works on Paper"
I noticed an exchange with a BCH/USDT 50% higher than coinbase's price for BCH so eyes watering bought some as a test. It was just 50 to see if it worked. It did not. The problem was the other exchanges BCH wallet was down so i couldn't deposit it in.
Not to be discouraged I have been looking at other arbitrage sites and opportunities and always have the same issue. Basically the wallet of the currency I want to trade in is down This was for EOS BAT and even LTC.
Is arbitrage possible or is it a case of if it seems too good to be true .....
Your mistake is one of most common in arbitrages.
Arbitrages are possible and profitable if you know what you are doing:
1. Always check deposit/withdraw status on both coins on both exchanges.
2. Always calculate the exchnage taker/maker trading fees + withdraw fees.
3. Don't mistake USD and USDT. USDT to USD vary a lot in term of arbitrages.
