We are talking in this blog about finding arbitrage opportunities in crypto. The catch is that, to make money in arbitrage, you have to trade coins for other coins. To do that, you'll often pay fees. Those fees will eat at your profits if you don't plan carefully. Let's walk through a sample.

Say you trade BTC for LTC. You will pay a transaction fee 0for LTC. So, say LTC costs 0.0039 BTC (as it is at the time of this writing), your total cost for 100 LTC would be both the BTC cost (0.39 BTC), PLUS your transaction fee. Binance charges a 0.1% fee on LTC transactions, so you would add that to your cost. Your cost is then 0.3939. 

To determine when to transfer back to BTC, then, you'll need your profit margin plus the additional transaction fee. Coinbase charges a 0.5% fee as of this writing, so you'll need a total return of 0.413595 just to break even.

Now that you have your breakeven price, add your desired return percentage. These coins bounce a lot, so even 10% has happened in one day.

Do the math, though: You need to make the whole transaction calculation this way:

1. Your desired LTC purchase + the transaction fee percentage

2. The LTC purchase total + the second transaction fee percentage

3. The final return to BTC + the third transaction fee percentage

4. PLUS your desired profit

Take a look.

Also remember that this article explaining how to compute all this is no substitute for solid financial advice. Work with your financial advisor, and don't bet the farm on crypto. It's squirrely stuff.
