Open testnet and connect metamask wallet

Once connected and signed, start clicking the PLACE YOUR BID button. Note that if someone chooses the same price as you, then you both fail. So 0.01 is not the best choice. This is also the charm of OK Gold.

### In the end, this is just the beginning, I hope everyone can be active in the community and witness the growth of our community.
