For those worried BTC might not go much higher. There was news circulating in social media about 80% of the total 21 million supplies have been mined and are in circulating in the market plus those are in idles. There are basically less than 5 million btc need to be mined...no need a racket science.. Supply and demand, bitcoin prices will soar high.
I think it's completely the opposite, we can actually analyze the available coin supply and how much BTC is moving around on a per-day, per-week, per-month, per-year, per-5-year period; we can actually analyze everything in Bitcoin because its publicly available. We can't do the same with proprietary fiat systems.
