Right now, one thing is for sure, Bitcoin value right now is very low and patiently waiting until the time will come that bitcoin price will became high. Many people really do believe bitcoins work thats why they are still buy a bitcoin and hold this until they can sell it in a higher price.
How can this be a low valuation if you consider what the price of bitcoin is exactly a year ago, i do consider this as high valuation, whether this is inflated is another topic, but it is not possible for a common man to purchase the whole bitcoin with his monthly salary, if bitcoin is able to do the fundamental use of being used as a currency the price will keep on increasing as long as there is demand in it.
