I would like to start this off by saying I'm a Crypto-supporter. Blockchain currencies and their supporting networks will make way for efficient, government-free, international transactions. Smart currency-contracts can control many aspects of life: loans, purchase agreements, wills/trusts, and securities. This concept, and the technology behind it is going to absolutely overhaul the modern day financial system as we know it, and there is no way to argue that because it is already happening.
Here is my current concern: Where is the value right now? As I'm writing this, I'm watching Ethereum bobble between $270 and $220 and Bitcoin bouncing around $2450.
Obviously there will be value in the future as the usability increases. But right now there are virtually no trustworthy or realistic wallets to use for purchases and there are virtually no businesses that accept these currencies. Bottom line, I can't go to the corner store to buy a stick of gum for .001 Ether.
Other than the chance to make a quick buck trading the funds, why is somebody purchasing cryptocurrency?
WHERE IS THE VALUE!? I AM A SILLY HUMAN! I can't feel it! I can't see it!
