ARBITRAGE : is the simultaneous purchase and sale of an asset to profit from a difference in the price. It is a trade that profits by exploiting the price differences of identical or similar financial instruments on different markets or in different forms. - Investopedia.com

So now you know was arbitrage basically is and now as to why you should care. If you are reading this, then you know about crypto-currencies and most likely are invested in one or more of these cryptos, either directly or indirecty. If you buy cryptos and/or trade them or simply Hodl, then you are directly involved. If you are merely here on steemit for the payouts in crypto (Steem) then you are indirectly involved in the crypto-currency movement. Either way, arbitrage does affect you because it affects the price of crypto-currencies.

In this case, I want to give an example of a crypto-currency that can be traded using arbitrage. In this case, Bitcoin Diamond (BCD) is in play. Right now you can find BCD on Gate.io exchange for around $20 US Dollars but on Binance you can sell it for around $98 US Dollars. Now don't forget there are trading fees and taxes to pay, but there is still a profit left over.

Now remember, this is not trading advice and prices can be extremely volatile rather quickly so take this as a simple trading lesson. 2018 is the year of the Crypto, so hang on for the SkyRocket Up!
