超大交易有一笔小额手续费。生成包含该交易的区块的节点会得到这笔费用。
There's a small transaction fee for very large transactions. The node that generates the block that contains the transaction gets the fee.
同一笔钱之后再次转出时，不会再次产生这笔费用。如果你的钱包里全是挖矿所得，又想一次全部转出，就必须在一笔很大的交易中，合并数百份每份 50 个比特币的挖矿奖励。完成这次合并后，以后再转出这笔资金时，交易里只需要一个输入项。
If the same money gets sent again, it won't incur the fee again. If all you have is generated coins in your wallet, if you send them all in one huge transaction, it has to bundle hundreds of 50 bc coins together. After that it's just one line to send the combined unit.
