Astonishing fees at coinbase !

[Joffjeff]

Hello

So, I bought for 2400 euros of BTC yesterday at coinbase.

I have transfered this money through SEPA and when the money has arrived, I have bought BTC.

Coinbase tells me that I'm going to pay 35 euros of fees which seems legit, I don't react. However, after the purchase, I only have 2150 euros of BTC. They took more than 10% of fees...

What do you think of this ? Can you explain that ?

Thanks guy and have a good day !
