Wow, hahah , this really made me laugh a lot, dont be so hard with him. Probably he does not have enough money to invest in bitcoin.
What's that ? A middle schooler allowance money ?
But yes, coinbase fees are very high at the moment, and that is not the fault of them.
The fees are very high because of the miners, and of course, of the entire blockchain, there are more transactions everyday and that is the main reason of why the transactions are taking more & more time to get confirmed.
We need more miners & more hashrate in order to be able to proccess those transactions faster, and to lower the fees, of course.
