How does your Botfund work?
Is it a market maker bot for CNY to BitCNY?

What are the expected returns per month / year?

I would be interested to buy more Botfunds.

Yes, it's a market maker bot for CNY : BitAssets.
The return per month is about 3% but it's not guaranteed. Please be reminded of the risk (of external exchange counterparty risk, being hacked and possible bot bugs) when you buy it.

Edit:

It's more of cross market arbitraging than market maker.
TRANFUND is doing exactly the CNY:BitCNY market maker and fiat gateway. https://bitsharestalk.org/index.php/topic,18170.0.html

内盘用的规则是按你说的价格成交,不是最优价格成交(当然我比较讨厌这个规则).
所以比如当前有5万0.005的卖单,有人用0.009的价格买了1万BTS,成交记录里看到的就是0.009成交了1万.但这1万是与0.005卖单成交的,所以比如你有0.006的卖单就不会成交.

囧 开设以来啊
原来我买的比例还挺高


风险的话 只要机器人不被黑 策略没有漏洞 不会亏吧

主要是被黑的风险和外盘平台跑路的风险,除此之外亏损基本不可能。
