We've seen Bitcoin, unanimously the most widely known cryptocurrency, rise to gains of roughly 730 times its late 2011 market debut. Most of which has occurred in just over 2 years time. Even after its meteoric rise, many call for continued pace of gains. From investing newbies to hedge fund titans, the positive, aggressive sentiment can be heard. But what does a logical assessment produce? Taking a look at the history of bubbles, debut of new asset classes, monetary policy, and wide-spread optimism jumbles this pandora's box into an unclear, cluttered assumption. Universal understanding is seemingly frail at best, news is hard to come by - especially for majority of price movements, fraud and/or undesirable 'bugs' dominate its mainstream news presence. Yet, the calls don't wane. What will make a "cryptocurrency" stable and viable? My knowledge and experience points to feasibility as a transactional asset. If we're able to escape the bars of traditional (fiat) currencies to facilitate trade, the efficiency gain would be worth billions annually. Not only from rate on float, but interest from in-transit funds, the savings could (would) be significant. After all, if an asset is not able to produce value or viable as a form of payment, what use does it have? What do you think? What will make BTC, other cryptocurrencies a mainstay? Is it worth the projected trillion dollar market cap? What makes it worth the $8,000 USD it has ascended to today?
