Very Short term you have a potential for profit. Anytime after that I believe it is a gamble because there are a few pretty big banks(Montei Dei Pachei, Bank of Italy, Bank of Greece, Deutsche Bank, ...) that are almost insolvent and if 1 goes down, it could cause a ripple (forgive my pun) effect.
I personally don't like it because it is used by the banks. I think it is a cool technology and if any form of banking comes out once/if the banks come out I believe it will be widely adopted... But personally I wouldn't risk my money
