From what I remember, Bitcoin only existed to prove a point that the value of money is only what people believe in -- given the GFC, this paved the way for Bitcoin and the other coins. I'm learning more about Bitcoin and I think it's a great idea. Yes they do have their quirks but the developers or whoever is running it, are working on solutions for this, hence the forks, and other things that I don't know the names of.
My particular interest in it, is the ability to send money internationally quickly and without fees. If I owe someone a measly US$50, I can simply send over the proper fraction of a Bitcoin and pay probably HK$1-2 as the transaction fee and it's good to go. Plus it has the exotic speculative point.
Would I put all of my money in the coins, absolutely not, they are not stable. Albeit I do think Bitcoin will go much higher, at least 10 times higher than its price today, given the news of upcoming futures and already quoting Bitcoin in smaller units, such as mBTC.
Plus, all of the other coins (1000's of them), these coins need miners and these miners are paid in coins, sometimes even Bitcoins, or miners will convert to Bitcoin, and thus supply will be even more limited.
Let's see what will happen--I do think there is a lot to learn from blockchain technology.
