There is a market for speculation, black and grey market finance, and gambling that will always give Bitcoin and other deflationary type cryptocurrencies value. People will "play" in these markets just like they play in casinos. The question is how much value and how realistic current numbers are. I have little doubt that if say 5% of BTC holders tried to cash in the price in USD would crash hard. Cryptocurrency in a broader sense is an emerging technology and will probably find other areas of utility. I feel like we don't even know what it is yet.
