I have a wallet in coinpayments.net. I converted 17 XRP to ETH using the site, which uses ShapeShift (https://etherscan.io/tx/0x7e07c18cec5c44a70fd0e79542dd68de029115bdb6366c0615ddab648fd01698)
As people of customer support from ShapeShift have told me, my transaction's exchange rate was 1 XRP = 0.00172507 ETH. However, in Coinpayments it says it's only 1 XRP = 0,001136291 ETH (880.05657211 XRP/ETH as they put it). Here's a pic: https://i.imgur.com/Y5XYHd1.png
So I've should have received 0,02932619 ETH (minus 0.00042 ETH on fees) but instead I only received 0.01931694 ETH. I know this are ridiculous amounts of money but I'm trying things before investing to see how it goes and learn from errors.
My previous transaction in Coinpayments was with changelly.com and I had zero problems.
How do you explain that 1 XRP = 0,001136291 ETH? I lost 34% of ETH in that transaction.
