Crypto currency is a con. All these apps are clownworld and completely demonic. They do not benefit. Otherwise you would make the cash yourself. You are online, why aren't you getting free money for your use of being on the fucking grid. See they only imprison far worse than cash. It is all credit with crypto. You have bought nothing of value. It has taken your value and given you debt. Imprisioning far worse than the lifestyles adopted by those communuties. They are also very restrictive in finding their own slice of freedom. The rules and obligations to their community are quite oppressive but free of the rat race. They live longer and are quite healthy. Crypto however is far worse than the simple barter they employ. Without credit and debt. Although I am sure their finances employ some forms of banking and credit for the national taxes they abide under. But the rest of their community are oblivious to them. Because both the amish and the kibbutuz rely on trade for trade and skill for skill helping each other found their communities. Which as you say are not strangers, and are firm in their beliefs and support for each other.
