Do you mean Bitcoin transactions spend too much time? I think it is not true, only for the transactions of a big number of BTC that spend hours. While for daily needs, It shouldn't need a big number of Bitcoin. Moreover, as far as I know, Bitcoin has its developers, who are always improving the system. Someday, we may see faster transactions for Bitcoin. So, don't be worried about the transactions time, it is not a too big deal. This won't make Bitcoin lose its purpose as a future currency.
