Fee Structure on Crypto Exchanges

Hey everyone,

I am relatively new to the world of crypto but have been in the world of finance for quite some time. I write algorithms, and for the most part these have been for forex or stocks. This is my first algo for crypto.

I am now however working on an arbitrage bot for crypto. What I am trying to gauge is, what kind of fee structure is present on crypto exchanges, and if it makes the bot worhtwhile at all. In my calculations, I am taking into account roughly 0.5% of the purchase amount of the underlying coin/token as fees. Is this a reasonable assumption? Or should I bump this up/lower it? Would appreciate your input.

Thank you!
