Bitcoin, like a other trading commoditities can't be perfectly predicted. Even at that; when to buy into the market or sell of it depends on your investment plans and financial status!
Futuristic rise shouldn't deter an investor from divesting if an opportunity with higher ROI is identified. Similarly investing in the misdst of dwindling price shouldn't deter an investor as there could be appreciation of prices in the distant future. These scenarios we're typical of Bitcoin few months hence!
Being a technology driven currency, it's potential to hostage regulated currencies in the near future ,is even enough to frustrate every natural investment behavior to the effect that the bad may now be courted S the Good .
Indeed, with Bitcoin and other related digital coins, the sacred investment status quo has no choice, but must drift asymmetrically!!
Be free to commit to an investment in Bitcoin . Either way, one is bound to be a winner , never a looser . Be assured of this ; albeit, in the long run.
