its fees are greatly reduced from the normie version.
but reporting your trades to the IRS is a built in feature of the platform.

fees are only important if you trade a lot but then you will bleed money out the ass anyhow.

This is only true if you do 200 or more transactions per year on coinbase, regardless of the trade size. In addition, you have to receive $20,000 or more from these 200 or more transactions for Coinbase to send you a 1099-B (which means they've been reporting your info to the IRS.)
