Last year when I heard about ethereum gold I put in a samll amount of eth. I thought I was late since it was over a year old. I got all of my eth back and then some plus the proce appreciation. It is battle tested and audited. A new wbtc contract is still very new. It could be some nice gains just like ethereum.
