Yes, absolutely. I'm a big proponent of and investor in bitcoin and MaidSafe coin.
Good point. neroden mentioned earlier (if I understood) that he mainly invests in companies with high fixed costs. A Buffett moat?
Yes. If you have the time and/or interest, I recommend this paper on the global savings glut by the Chief Investment Officer (equities) at Fidelity. If he's right, then interest rates/the cost of capital will remain low for the foreseeable future:
The global savings glut - Fidelity
"Global gross savings are about 24% of global GDP and, when adjusted for depreciation of fixed capital (savings wealth consists of fixed assets as well as financial capital), we are still seeing savings of 11% to 12% on a net basis, which is substantively in excess of nominal economic growth."
I'm definitely in this camp. Financial bubbles happen when we get a combination of cheap capital and innovative technology. The internet hype created the last great equity bubble. I think a whole host of new technologies (AI, VR, gene sequencing, renewable energy, autonomous/electric vehicles, 3-D printing, p2p finance etc) will capture the investor imagination and fuel the next. I also think it will dwarf the internet bubble - just look at how overvalued bonds got 2 years ago when interest rates went negative.
