Coibase charges a 25% fee on staking rewards.

Many people seem to be unaware of coinbase's fees hidden in their staking user agreement, so I just wanted to highlight this fact so everyone is aware.

I'm linking the ETH staking User agreement here in so anyone who wants to give it a full read can do so. Staking on coinbase also comes with certain risks and the lacks guarantees that makes me unwilling to stake on their custodial platform. I recommend staking in a wallet you control the keys to, but that is a choice for each individual. Please give the terms a look if you use/stake using coinbase.

As always, do your own research and I don't know shit about fuck.

Edit: I believe the rates quoted by coinbase already have their fee factored in. I have attempted to contact support looking for clarity on this topic and have yet to receive a response.

Edit2: it appears the staking fee varies by cryptocurrency. Some are higher than others.
