Increments of 0.001BTC will help us find the true secondary market price of these coins a lot easier. You spotted your mistake early on and I believe you should be able to modify your OP.
Also please include whether or not you will be accepting newbie bids freely or require a deposit. These lower denomination coins are an easier entry point for new collectors and we need to properly outline our rules.
With that I will change my bid in the OP to .001, unless there is overwhelming objection I'm not looking to start drama.
As far as newbies bidding, I'm fine with anyone bidding freely who has been a member since 2018 or before. Newly made accounts in 2019 need to sign a message from a wallet with at least the amount in their bid.
Good?
