挖矿活动会逐渐集中到这些地方：
Some places where generation will gravitate to:
1) 成本最低或不用付费的地方
1) places where it's cheapest or free
2) 出于理念、愿意贡献算力的人那里
2) people who want to help for idealogical reasons
3) 想直接获得一些比特币、不愿费事去交易购买的人那里
3) people who want to get some coins without the inconvenience of doing a transaction to buy them
确实存在合理的低成本场景。凡是用电取暖的地方，挖矿基本不会增加额外成本，因为电脑产生的热量可以抵消一部分电暖器耗电。很多小公寓为了方便，本来就使用电暖。
There are legitimate places where it's free. Generation is basically free anywhere that has electric heat, since your computer's heat is offsetting your baseboard electric heating. Many small flats have electric heat out of convenience.
取暖油有多贵？油价这么高，如果取暖油真的比电更贵，那么挖矿的净成本甚至可能是负数。
How expensive is heating oil? With the price of oil so high, if it's actually more expensive than electric, then generating would have negative cost.
还有孩子把它挂到父母的电费单上、员工挂到雇主头上、僵尸网络等等。
There's also kids putting it on their parent's power bill, employees their employer, botnets, etc.
第 3 种情况适用于小额需求。如果你只需要一点零钱来完成偶尔的微支付，专门去交易所兑换并不划算。我认为，这是它相比法定货币的一个优势：与其让货币发行收益全都归一个大型机构，不如把它拆成方便使用的小额资金，分给真正需要凑一点零钱的人。
Case 3 comes into play for small amounts. The overhead of doing an exchange doesn't make sense if you just need a small bit of pocket change for incidental micropayments. I think this is a nice advantage vs fiat currency, instead of all the seigniorage going to one big entity, let it go in convenience amounts to people who need to scrape up a small amount of change.
