1. Bitcoin is fast, decentralized internet based currency which means it can't be controlled or banned by government.
2. Transactions are very cheap, in most cases you will pay less than 1 cent for sensing BTC to any place in the world.
3. Bitcoin is great speculative tool, if you buy 1 bitcoin now it could be worth 50% more in a 2-6 months.
Don't want to rain on your parade but
1 bitcoin isn't really that "fast" compared to other ways of internet payments (PP.skrill,AP..just to name a few), even tho it has great advantage over them as well
2 transactions are much more expensive then what they used to be, just try making a 0 fee transaction these days.. it used to work..
3 great thing to speculate on - definitely , but it could just as easy go down 50% in same time range.
