I agree, bitcoin is similar to gold but the only difference is that bitcoin can change fast, people invest money into gold and just leave it for years to come back and find that it has not changed a lot, however bitcoin has the potential to get up very much in the next few years, I mean look at it in a couple of month it was able to get from 700$ to 1000$.
Gold is certainly manipulated down by the authorities (at least two serious books have come out with the evidence.) Over the decades, gold is still one of the best investments. It protects you pretty well, long-term, against inflation, since the more money and debt get multiplied, the more money savers will have to buy gold. Bitcoin is kind of like gold, but not quite as tried-and-true.
But if I were to guess, I'd say Bitcoin is actually manipulated up by the imperial elites at this point.
When gold was 'demonetized' in 1971, some mainstream economists predicted its value would drop from $35/oz to whatever industrial and jewelry-based demand would support. (Like silver in the 1870s.) What happened was the opposite. Apparently, it was one thing for major states to go from gold and silver to gold only, but another when they go totally fiat.
Beware of speculative thinking... Think long-term, and look mainly at fundamentals.
