Bitcoin will grow in value. Depending on how much Bitcoin you own, you'll become wealthy. It's a new currency, so it'll take time to establish itself, but once it does, it'll be the one-world currency.
Bitcoin is no longer a new currency anymore,Just buying a singl bitcoin wouldn't make you wealthy soon enough.Bitcoin was sometime $3-5 and now its $500+ and even had reached more than $1k once.It depends upon the market demand.
