BIS:比特币必须摆脱工作量证明机制
国际清算银行(BIS) 1月21日发布的研究报告显示，比特币的问题只有通过摆脱工作量证明(PoW)机制才能解决。该报告指出，当未来比特币的区块奖励降至零的时候——考虑到新比特币的生成数量有限——单凭交易费用将不足以支撑挖矿费用。该研究进一步指出，虽然像闪电网络这样的第二层解决方案可能有所帮助，但“唯一的根本性补救办法是摆脱工作量证明机制。”
BIS: Bitcoin Must Depart From Proof-of-Work
Bitcoin’s (BTC) problems are only solvable by departing from a proof-of-work (PoW) system, according to research published by the Bank for International Settlement (BIS) on Jan. 21.According to the paper, when in the future Bitcoin’s block rewards fall to zero — given that only a limited number of new Bitcoin will ever be created — transaction fees alone will not be able to sustain mining expenses. The study further notes that while second-layer solutions like the Lightning Network could help, “the only fundamental remedy would be to depart from proof-of-work.”

税务噩梦:在瑞典交易 1 万个比特币的瑞典男子需要交纳近100万美元的净税款
瑞典加密货币交易员 Linus Dunker 收到瑞典税务局（STA）开出的高达 100 万美元的税务账单，他感到十分震惊并声称这种征税要求“不合理”。据 Dunkers 说，他被收取的税费几乎是他所获得的总利润的300%。然而据悉，这起案例只是 STA 受理的与加密货币相关案件中的一例。自从加密交易在瑞典开始流行以来，STA就多次表示对处理加密货币相关事务感兴趣。仅在2018年，STA就对多达 400 名瑞典加密货币交易员的交易活动展开了调查，调查人数是2017年的10倍。
Tax Nightmare: 10,000 Bitcoin Trades Net Swedish Man Nearly $1 Million in Taxes
Linus Dunker, a Swedish crypto trader, was shocked to receive a bill for almost $1 million from the Swedish Tax Agency, claiming that the tax demand is “unreasonable.”According to Dunkers, he is being charged 300 percent of his total profits. The case is one of a growing number of cryptocurrency-related cases being taken up by the agency. The STA has increasingly indicated an interest in prosecuting cryptocurrency cases since crypto trading attained popularity in the country. In 2018 alone, the STA opened investigations into the activities of up to 400 Swedish crypto traders – 10 times more than the previous year.

区块 7,100,000 的高度已经通过，这意味着难度炸弹将再次升级，我们将开始发现区块的生成时间越来越慢，大约会在18到20秒之间，直到区块达到 7,200,000的高度。
Block 7,100,000 has passed which means the difficulty bomb will step up again and we'll start to see slower block times. Probably around ~18-20 seconds until 7,200,000.

2019将是一个好年头。
期待有更多的白皮书发布，并将顺利扩展比特币，使得那些造出冒充 BTC 的币的家伙们开始认识到他们的假比特币分叉是多么差劲。
2019 will be a good year.
I look forward to papers being released and scaling Bitcoin as the BTC sham coins guys start to see just how screwed their fake bitcoin fork is

比特币能腾飞是因为它宣扬思想观念。以太坊能腾飞是因为它宣扬实用性。
产生谬误的地方在于认为其中一方是真理，一方是邪说。新的社会建构需要二者缺一不可。
Bitcoin took off because it preached Ideology. Ethereum took off because it preached Practicality.
The fallacy is in thinking one is RIGHT and the other is the WRONG. A new social construct needs BOTH.

比特币ATM对新用户来说是个好工具，通过它可以很容易地买到比特币或其他加密货币。
大多数我见过的ATM存在的问题是费用高和汇率低。使得从ATM购买加密币通常比从交易所买贵得多。下一步要解决的正是这些问题。
Bitcoin ATMs are good for new users and it's easy to buy Bitcoin or other crypto with it.
The problems with most that I've seen are high fees and poor conversion rates. It is often much more expensive than exchanges. Next step is to fix these issues.
