Bitcoin's purpose isn't for investing. People might choose to invest and speculate on the future value of Bitcoin but, among other things, Bitcoin's purpose is a currency that is decoupled from a central government.
Not very feasible, right now. There are some technical hurdles that can be overcome with some improvements in the code which will drop the transactions fees to almost nothing.
For now, Bitcoin seems to be taking shape as a store of value, like gold. Another, more updated crypto currency, might take over as day-to-day currency while Bitcoin is the larger value store.
Hard to say how things will shake out but it's surprisingly still the early days of crypto technology.
