Coinbase is a steal

Today I was on the street and made a purchase on my cell phone at Coinbase. I already knew it was something expensive (1% fee!), but I saw an opportunity while I was at the restaurant.

The problem is that, while the receipt informs the quotation of 93k, the ticker shows 91k.

That is, it is only possible to earn money on Coinbase Advanced, an environment in which the fee is reasonable. But with this type of theft, things get complicated.
