之前提到,我买了一些Steem,后来索性把它们全部变成了Steem Power (SP),变成长线投资。变成SP后,要再拿出来变现,需要Power Down,这个过程需13周时间:即每周取回来1/13的SP变成Steem. 我为什么这样做呢?
首先,SP拥有者(包括被代理的SP)投票点赞别人时,能按SP的拥有量成比例分享相应文章收入的25%,这就鼓励SP拥有者要多点赞好的内容,不但能给别人带来收入,也能给自己带来收入——尤其是SP多的时候,就像SP页面如此解释SP:
Influence tokens which give you more control over post payouts and allow you to earn on curation rewards.
When users vote on content, their influence over the distribution of the rewards pool is directly proportional to the amount of SP that they have. Users with more SP have more influence on the distribution of rewards. This means that SP is an access token that grants its holders exclusive powers within the Steem platform.
除此之外,我查阅了最新修订版的白皮书(Steem White Paper,Steem白皮书中文翻译版),发现其中有这样的说明:
SP holders are also paid interest on the balance of SP that remains vested. 15% of the yearly inflation is paid to SP holders as interest. The amount of the interest that they receive is directly proportional to the amount of SP they hold relative to the total amount of vested SP across all users.
也就是说,每年新发行的Steem币,将会有15%分给SP持有者(注意,不是年利率15%!),分配原则按拥有SP量成比例获得,相当于每年SP拥有者还能获取一定量的“利息”。当然,我看重的不只是这点利息,主要是觉得Steem现在的币价被低估……
那么,每年Steem的新发行量是多少呢?白皮书也有说明:
Starting with the network's 16th hard fork in December 2016, Steem began creating new tokens at a yearly inflation rate of 9.5%. The inflation rate decreases at a rate of 0.01% every 250,000 blocks, or about 0.5% per year. The inflation will continue decreasing at this pace until the overall inflation rate reaches 0.95%. This will take about 20.5 years from the time hard fork 16 went into effect. 75% of the new tokens that are generated go to fund the reward pool, which is split between authors and curators. 15% of the new tokens are awarded to holders of SP. The remaining 10% pays for the witnesses to power the blockchain.
从2016年12月份开始,也就是第16次硬分叉开始,Steem起始年通胀率是9.5%,然后每年递减0.5%,直到20.5年后通胀率保持在0.95%——希望能存活那么长时间。18年后变成1%的话,Steem的总量也不过现在的3倍不到,相比之下,美国政府从2008年到2015年7年时间,美元总量增长了4.59倍。
本文撰写的时候,Steem已经生产出来的数量为240,724,601个,2.4亿个,按今天Steem价格1.49美元,总市值约为3.58亿美元,Steemit目前的注册用户数量仅为30万,相当于每个用户平均拥有1200美元左右。
值得注意的是,SBD(Steem Dollar)理论上也有利息,白皮书上这么写的:
A percentage of SBD value is created at an APR set by the witnesses and paid to SBD holders as SBD.
但实际上,Wallet页面上是这样写的:
(SBD) Tokens worth about $1.00 of STEEM, currently collecting 0% APR.
也就是目前的利息率为0.
总结:
- 拥有SP,不但点赞别人能获取收入(SP越多收入越多),而且能拥有“利息”。
- 按现行规定,Steem有一定通胀率,最终保持为很小的0.95%。20年后Steem的总量也不会超过现在的3倍。
- 现在每个Steemit用户名义上平均价值约为1200美元。
- SBD理论上有利息,但现在的利率是0.
以上分析基于现有白皮书,如果将来规则有改变,则需要另外计算。而这些规则是有可能变化的,比如,之前Steem的通胀率是每年200%,当时看到这数字我断然不敢投资Steem。
BTW,Steem的白皮书写得比较详细,但分析起来依然不是很明朗,主要是因为Steem的设计原理比较复杂……
