Betting on any currency is speculation, not investment. And although currencies may be useful, that doesn't mean that buying more currency than you need for practical purposes is going to turn you a profit.
Indeed, the opposite often applies. A good currency has low volatilty and is easily exchanged for other things. The US dollar has been a great currency for decades, but buying lots of dollars wouldn't have made you rich, because dollars are not productive assets. They just sit there. No serious investor parks lots of money for long periods in currencies; it's better to buy productive assets (e.g., stock index shares) in that currency.
If Bitcoin ever becomes a good currency, it too will be a bad choice for speculation. A financial company with Bitcoin infrastructure might be a good investment. But Bitcoin's high volatility, which makes it great for speculation, will have to vanish if it ever becomes a decent currency.
