Dr. Shiva is wrong about #Bitcoin. Here's my take, what's yours?
I have a Bitcoin node myself. Most Bitcoiners I know have one. It was made so that anyone could. Bitcoin Cash, a fork attack on Bitcoin who wanted to make it harder for everyone to mine it. Basically lost most of its value... One time, China had most miners. Then they banned it. It was moved to other parts around the world. There's miners in Africa, USA, Russia, back in China. Everywhere. There's Bitcoin miner pools, where everyone shares the mining work together. A new one is called "Blue Ocean" that is even harder for governments to track down, because they don't have any profit themselves.
Even if Vodaphone and T&T took over most miners, they could STILL not change how Bitcoin works. And that is the whole thing... It cannot be printed. Working people doesn't loose their value with Bitcoin, compared to the fiat system. Made by the bankers. Who can print any amount.
If they take it over, then make a change to Bitcoin. The whole blockchain would be "forked". Then people would be able to choose which one to use. This happened with Bitcoin Cash. I got both Bitcoin and Bitcoin Cash because of this. Me and most others, sold our Bitcoin Cash and bought more Bitcoin instead. In the original one, made FOR the people.
