As such he would at least honor the bid for 350BTC which was the highest one inside his own deadline. With him apparently having enough reels keeping his word would have cost him 20BTC, he could still sell the other one for 370.

He was too greedy to do that.

Also keeping a well visible legal notice on a web shop doing business for hundreds of thousands of dollars is not a "nice to have" feature. You are required by law to do so, so your customers know who they are dealing with.
Founding a limited liability company costs 300 Euro in Finland, that should be manageable. What if you send Punin you BTC and next day he has a car accident?
Companies not registered or not paying tax or other shady businesses will fuck up sooner or later, giving your customer a little transparency is not too much to ask.

Please upgrade your website with the necessary legal details.

There is also a thing in Finland called lawsuit.

"A case where two or more people disagree and one or more of the parties take the case to a court for resolution".

It really hurts me but I guess from your cocky behavior that we will need to go this path. Unfortunately it's not the fastest one which is unpleasant especially in ASIC mining business.

I suggest we both sleep over it and if you feel like we can continue talking tomorrow.

Please follow the rules you made yourself. What is a deadline good for if you bend it as you wish?
