Not sure about all the announcement and wall tactics, but that is what drew me to Bitcoin early on. Some rich person could just take the price anywhere he wanted and change the value perception.
Only, back then the ecosystem was a shadow of what it is now. With all this infrastructure being created, a few fund managers could slowly push it and the "fundamentals" would keep up.
What fundamentals? There aren't any revenue, debt, P/E, earnings, or EPS metrics to value this currency!
Technical analysis on the trading, the swings, the moving day averages and stochastics, maybe...but fundamentals? What fundamentals are used to evaluate the Dollar or the Euro?
