Information outreach: advantages of digital currencies such as denominated currency
1、周期明显。大部分主流矿币，都有着固定的减产周期。例如比特币，每四年的生产速率会减少一半，2020年5月12日前四年，平均每十分钟出产12.5枚比特币，而在此后的四年，相应的时间内只会有6.25枚产出。这意味着代币价格也会以四年为周期宽幅波动，一般减半后两年会上涨，减半前两年会下跌。这个趋势在过去三个周期内都是生效的，长期投资用户可以以此为指标进行操作，高抛低吸获取收益。
Most of the mainstream mineral currencies, for example, have a fixed production reduction cycle. Bitcoins, for example, halve the production rate every four years, averaging 12.5 bitcoins per ten minutes by 12 May 2020, and, for the next four years, only 6.25 bits of output.
2、交易便利。目前所有的数字货币交易所，都是7*24小时交易，一般情况下不会停机，投资者可以在任何时间快速兑换不同代币。入金渠道也非常便利，大部分交易所都提供法币交易区，并作为中介方(免费)担保投资者间的交易，这意味着投资者可以安全地使用法币购买数字货币。
2. Transactions facilitation. All digital money exchanges are currently 7* 24-hour transactions, which usually do not stop, and investors can quickly convert different currencies at any given time. Access to money is also very convenient, with most exchanges providing zones for transactions in French and guaranteeing transactions between investors (free of charge) as intermediaries, which means that investors can safely use French to purchase digital currencies.
3、市场成熟。除了现货交易外，许多交易所还提供了诸多衍生品交易服务，当然这都是比较高阶的玩法，小白用户暂时不需要考虑。
3. Markets are mature. In addition to spot transactions, many exchanges offer a number of derivatives trading services, which, of course, are relatively high-level games that white users do not need to consider for the time being.
4、体量足够。截至目前，仅仅比特币的总市值已经达到三万亿人民币，属于历史最高规模，比茅台的2.35万亿市值还要高。加上其他数字货币的市值，这个行业的规模已经相当庞大，不再是极早期的弱不禁风状态，代币价格在一定时期内相对稳定。
To date, the total market value of Bitcoins alone has reached RMB 3 trillion, the highest in history, and is higher than the market value of $2.35 trillion in Maotai. Together with the market value of other digital currencies, the industry is already quite large and is no longer an early state of weakness, and the price of the tokens has been relatively stable for some time.
投资比特币等数字货币的劣势
The disadvantage of investing in digital currencies such as bitcoins
1、政策风险。比特币等数字货币以去中心化为典型特征，极大程度上是为了规避监管，但铁拳不可避免，政策风险始终是行业的痛处。重要经济体的政策变化，会极大影响行业的发展，例如去年我国提出要大力建设区块链基建，比特币当日大涨40%，许多做空的投资者爆仓受损严重。
1. Policy risks. Digital currencies such as bitcoin, typically characterized by decentralisation, are largely designed to circumvent regulation, but iron fists are inevitable, and policy risks are always the pain of the industry. Policy changes in key economies will have a significant impact on industry development, such as last year’s initiative to build blocks of infrastructure, a 40 per cent increase in bitcoin that day, with many empty investors seriously damaged.
2、短期高波动。即使没有政策影响，比特币价格短期内依然具备非常大的波动性，上下5%波动可能仅仅发生在五分钟内。也因此业内戏称，币圈50%以内的波动都属于横盘，非常考验投资者的心理承受能力。
Even without policy implications, bitcoin prices remain very volatile in the short term, with up and down 5% likely to occur in just five minutes. Thus, intra-business claims that currency fluctuations within 50% of the circle are across the board and very test investors’ psychological resilience.
3、骗局横行。行业发展早期，泥沙俱下是非常正常的现象。业内骗局主要分为两种，一种是交易所诈骗，把投资用户骗进来后，伪造k线导致用户爆仓获利;另一种则是资金盘与数字货币的结合，所谓模式币，往往打着区块链技术的名义，行传销诈骗之实。许多投资者被骗而不自知，这让笔者非常难过。
In the early years of industrial development, it was very normal under the mud. There were two main types of intra-business scams, namely, exchange fraud, which led to the counterfeiting of the k-line after the investment user had been tricked into it, and the combination of funds and digital money, often in the name of block-chain technology, which spread fraud. Many investors were deceived, which made me feel very sad.
