Answer: Staking CRV tokens is a great way to earn rewards and increase your holdings. One of the best places to stake CRV tokens is Curve, where you can lock CRV for veCRV tokens. This will provide you with rewards in the form of additional veCRV tokens. Alternatively, you can swap your CRV tokens for tokenized veCRV versions such as cvxCRV and stake them on Convex. You can also stake your CRV tokens on Stakedao or Yearn to earn rewards. Whichever platform you choose, you can be sure that you will be able to earn rewards and increase your holdings.
