# Gimmick or Trick ?Memecoin之Reflection Token **Published by:** [Mobius](https://paragraph.com/@0xmobius/) **Published on:** 2021-12-19 **URL:** https://paragraph.com/@0xmobius/gimmick-or-trick-memecoin-reflection-token ## Content 何为Reflection?简单理解,是对代币持有者的奖励支付。以最近大火的Mongoose Coin为例,在每次转账发生时,都会向交易发起者收取13%的税费,其中6%分配给代币持有者作为奖励。 Reflection的设计看似平平无奇,实则暗藏玄机。首先,fomo的散户在未发觉交易滑点的情况下,梭哈进场,那必然秒被套10%以上。在持有成本增加30%左右的情况,散户的持有周期会变长,同时有更大概率补仓;另一方面,由于分红机制,持币数量的增加营造出持有回本甚至暴富的幻觉,散户hold的心理压力能随之缓解。基于以上原因,当散户更有动机成为holder而非trader,也就给了项目更大的空间运营(aka CX)。交易Case,以Mongoose为例交易前rTotal = 115792089237316195423570985008687907853269984619000000000000000000000000000000tTotal = 69 * 10**30currentRate = rTotal / tTotal = 1678146220830669601999536757454230066353405952我买入69 * 10 ** 28个token后tAmount = 69 * 10 ** 28 tFee = tAmount * 1 // 100 tLiquidity = tAmount * 12 // 100tTransferAmount = tAmount - tFee - tLiquiditytFeeTotal = tFeeTotal + tFeerAmount = tAmount * currentRaterFee = tFee * currentRaterLiquidity = tLiquidity * currentRaterTransferAmount = rAmount - rFee - rLiquidityrTotal = rTotal - rFee 根据上面的公式可得:rTotal = 115780510028392463803317188205061473665812146117931200000000000000000000000000合约地址_rOwned增加值为rLiquidity我的_rOwned增加值为rTransferAmount = 1007391176364650962080321915499774308831949592985600000000000000000000000000更新currentRate后currentRate2 = rTotal / tTotal holdAmount = rTransferAmount / currentRate我的Token持有量为600360036003600367603601637376,交易滑点为13%currentRate2 / currentRate1 = 99.99%,即1%的交易滑点作为分红分配给holderLet’s Fomo not invest参考2021年12月19日21点左右,Mongoose市值大约1 Billion,成交量大约9 Million。假设币价维持现状,根据滑点和分红可得回本周期约为9个月。但由于Memecoin的波动率极大,如此长的回本周期基本可以放弃靠分红赚收益的幻想,投资时还是要聚焦社区的基本盘。简而言之一个字,冲。 ## Publication Information - [Mobius](https://paragraph.com/@0xmobius/): Publication homepage - [All Posts](https://paragraph.com/@0xmobius/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@0xmobius): Subscribe to updates - [Twitter](https://twitter.com/___Mobius___): Follow on Twitter
