比特币在现实支付中的应用是大势所趋，但我这儿点疑问，望大神解惑。
首先就是支付确认时间问题，比如现在吃饭买单，现金付完直接走人，而用比特币呢，是不是还得在支付后坐那儿等上几分钟，等至少得有一个确认什么的吧，那样才算支付成功。这样不就很不方便么？
不等确认又怕出现什么双花的问题。
再有，比特币的应用越来越广泛，整个Blockchain的大小也会极速增加，只增不减，会不会到了一定时间大得让人接受不了，比如50年后，整个Blockchain的大小会是多少呢？

小额应该问题不大，双花应该是在不同地点,同一时间用同一钱包花btc,这难度有点大。大额等确认。
Blockchain的大小极速增加，10年后说不定硬盘都几千T了，怕什么。

现实生活中用手机支付比特币非常方便。 将来绝大多数商家会接收零确认。 几秒钟就完成支付。  而且手机比特币钱包只用几M字节就行了， 占不了多少内存空间。  想信将来会有更多、更好用的比特币手机应用钱包。
