Samuel, unfortunately, *you cannot check the original buy price on your MEW* **but you can still see it on the exchange**. In order to do that, you would have to go to the exchange you originally purchased your coin from and check your Order History. Within your account, you will be able to access your trade prices and see exactly what you bought your coin for, whether it’s in USD, USDT, BTC, or ETH.

This is because coin price is not universal; it varies between exchanges. As an example, see the screenshot below:

If you look on the far right, you’ll see the exchanges (listed under **source**) that can exchange Ethereum. I’ve also highlighted the price column — you’ll see that on each exchange, and also between exchanges, prices of Ethereum vary based on how you purchased it (whether it’s ETH/USDT or ETH/BTC, for example). For a wallet like MEW, which does not have access to your exchange data (information about things such as when you bought it, what pairing you used, which exchange you bought it from), it would be impossible to tell you what price you bought it at.

This difference in pricing might lead you to wonder if you can take advantage of the price differences to make profit off the spread — yes, you can, and people do it. It’s called arbitrage (if you didn’t know). You can Google more about it. Be careful, though — it’s very risky, and also, there are many factors to consider beyond the price such as transaction fees, withdraw fees, possible deposit fees, and transit time. These will all play a role in your ability to effectively leverage any arbitrage opportunity.
