Current prices of BTC, ETH, BNB (date 02.19.2018 22:23):

• ETHBTC: 0.08416900
• BNBETH: 0.01178700
• BNBBTC: 0.00099240

This means you can buy/sell:

• 1 ETH for 0.0841690 BTC
• 1 BNB for 0.0117870 ETH
• 1 BNB for 0.0009924 BTC

If I want to buy BNB, first by buying ETH for BTC, and then by buying BNB for this ETH I get:

1 BNB = 0.0117870 ETH = 0.011787 * 0.0841690 BTC = 0.0009921 BTC

We can sell 1BNB for 0.009924 BTC, so our profit (without fees):

0.009924 - 0.0009921 = 0.000003 BTC

Total fee = 0.015%

Total fee = 3 * (0.009924 * 0.015%) = 0.000005 BTC

So we can see that this trade is not profitable
