Reddit – Dive into anything

I’ve seen lots of posts about people complaining about the “hidden” cost of buying bitcoin between Coinbase Mobile and Coinbase Pro. Here is my stupid little calculator that will compare the cost of various buys and sells against pro.coinbase.com. It can run in any python console or on android as well with the help of a launcher

Coinbase Mobile seems to run at about a 3.5 % premium compared to Pro which usually only has about a 0.15-0.20 % premium.

Basically, Coinbase Mobile seems to be running a 3.5% premium over just using Coinbase Pro. The “Free Conversion” feature runs about a 1% premium over just doing it on the Coinbase Pro exchange. If you have to use mobile, CashApp is substantially cheaper.

Note: I’m only referencing Coinbase Pro. Most of the time, most of the US exchanges BTC/USD order books are within 0.10% of each other. There is arbitrage, but for the numbers I’m looking at, I consider it mostly insignificant.

Enjoy!

Disclaimer: Costs occur in many forms. The costs on the fee schedule are one of those costs, but others may include the size of the order book spread or origination costs.
