I remember friends and collegues who were all crazed when the bubble started. They were buying, spamming on facebook about how cryptocurrency was the way to go and how they have a high R.O.I etc. But I knew and just like physics, all increasing bubbles eventually burst. Afterwards it was the bankers fault. All various conspiracy theories etc...
