Tom,

It's clear that you have some rather large gaps in your knowledge of Bitcoin=
, its rules, implementation and game theory. I highly encourage you spend so=
me time learning more about these things before continuing posting here.=20

https://www.reddit.com/r/BitcoinBeginners/ is a good place to start. It's a s=
afe place where you can ask any question you want without fear of being laug=
hed at.

Kind regards,


Jean-Paul
