How can I trust this collection?
You can check our smart contract and you will see the cashing out function "withdraw", that gives 95% to the verifiable wallet address of The Giving Block Campaign. So even if this was a scam (which is not) at least you gave 95% to charity. Unfortunately this only applies to Ethereum blockchain. On Polygon blockchain, this is not yet possible, but we are trying to figure out a solution.
Furthermore Juanjo Lopez is a real artist that has always created art and will forever do so. You can stalk him via Google and get in touch with him via Twitter.
