More hassle than it's worth? Photographer: Dan Kitwood
The Bitcoin rate spike, still alive despite bitter divisions in the community
that supports the cryptocurrency, has laid bare the biggest problem with
Bitcoin: Compared with fiat currencies, it's painfully inconvenient and
expensive to use as a means of payment.
儘管比特幣社群分裂，它的價格還是上漲
最大的問題：和法幣相比，它作為支付的工具
使用上有夠痛苦，有夠不方便，成本有夠貴
Bitcoin is set up to reward users for verifying transactions. Miners who
package transactions into "blocks" receive two kinds of rewards: The
additional Bitcoin they produce by using their hardware to solve mathematical
problems (an income stream that will eventually cease since 21 million
bitcoins are the maximum that can be mined) and the transaction fees paid by
users to get their payments into blocks.
簡介一下礦工的角色，這個大家都知道就不翻
The Bitcoin system is designed around scarcity and its traditionalists insist
on keeping the block size small (rebels who did away with that tenet founded
an offshoot, Bitcoin Cash, earlier this year). Their reasoning is that only
people with more computing power can live in a big-block world and going down
that path would make Bitcoin less democratic. But that horse has bolted:
Mining is already largely the province of people who invest significant money
in equipment and the huge amount of energy required to run it. As Bitcoin's
exchange rate rose rapidly and more people wanted to get in on the boom,
getting into blocks became difficult, and miners prioritize transactions on
which users are willing to pay a higher fee. It works a bit like Uber's surge
pricing, except the user sets the fee based on how long she's prepared to
wait for the transaction to go through
