The first thing you need to do is understand basic, core fundamentals of life. These include God, family, relationships in general, live and let live, and more. The basics are found in the USA Constitution, Amendments, court cases, and the Bible.
The next thing you need to do is ask yourself what Bitcoin has to do with it. Don't get hung up on the novelties of Bitcoin. Off-grid will make it so that your private community might be separated from the basic blockchain. But even if you are connected, you might want to use Colored Coins to keep your batch of bitcoins private.
Next, you need to think about regulation by government. You have two choices:
1. Go where there is no government, or where government doesn't exercise its control, and really start over from the ground up;
2. Limit governmental influence and regulation, but remain where you are under the protection of the strength that government has, internationally speaking.
Forget Russia. Government is dictatorial over there. They can take over in a minute if they want.
Britain is too small.
Canada is good, but their freedom protections are too interlaced with governmental words to make it easy.
The best ideas are USA PMA (private membership association), or seasteading if you can afford it. Btw, you will absolutely need a PMA if you do it in the States.
Also, you need to ask yourself and your group, how many conveniences of life do you want to give up. True off-grid might include giving up gasoline, and making your own alcohol... and all kinds of stuff. Dig up copies of the old
Foxfire books, and see what it is really like before you decide how off-grid you want to get.
Let me say again... if you want to do it in the States, you really need a PMA. If you don't do it under the auspices of a PMA, Government will regulate and tax you out of existence, or into prison. Consider
Waco. Or else you will simply become something like any town or city... nothing changes. The advantage of a proper PMA is that you become a government within the land, separate from the formal Government.
If you set yours up well enough, or modify its base the right way before it gets too big, enough people might join your group so that it becomes the foundational government in America, and the U.S. Government becomes the PMA.
