I've asked this for quite some time and still no one was able to answer. If the power has shifted to an elite who controls the great majority of the currency, and has the power to withdraw/dump coins (basicaly influencing the supply side of the market, and control the value) - I'm pretty sure there are people/organizations who invested into such positions - and have the power to simulate value and draw people into this gold rush... Where is the line drawn between this and a scam/fraud? Is it when the control party withdraws all the value from it and dumps it? For as long as everything is being valued in a positive way, everything is fine?
