It's a supply and demand scenario. As long as demand keeps rising, the value should rise with it. The current drop in price is directly related to a lack of confidence and therefore investors (old and new) are selling rather than buying. Spending Bitcoin on physical products and/or services is a way to cash in on the value without trading. Plenty of value in Bitcoin, more and more places are listing Bitcoin (and to some extent other cryptocurrencies) as a method of payment, the demand is not going away, it is just slowing to make a correction on the over valuation during 2017. From buying a pizza with Bitcoin, people are now using it to buy property, that's progress and a positive sign for the future.
