How Coinbase became so big?

Hi guys,i just wanna say something about Coinbase,they have crazy fees and this is just ridiculous,also if you are Bank of America Customer you have to pay for Foreign Transaction.Thats how you becoming so big so fast on the back of all the average people,so that's how it is.We have to do our research way way better because till we fight for some small bread some companys monopolize the whole market that's what exactly happens with F...base if you wanna pay all these fees yeah trust them.Good luck to everybody and watch out for The Sneaky type wallets like F...base.Peace
