It's a high risk investment. Trading is unpredictable, sometimes you can't make profit or worse, you can lose money, and until recover the money it takes some time... 0.4%-0.5% daily return is too high. If your bot is really good and has an advanced strategy you could use your own money and make all profit for yourself, why not?
The bot has done extremely well running on big pairs in poloniex. On a test period of 2 weeks, the bot averaged to about 1% a day (nearly 14% for 2 weeks), but I can't promise 1% daily returns, as I think that is unsustainable in the long run. The bot is not made by me, but I can assure you it is much more powerful than pingpong bots such as C.A.T. I don't run the bot all day on my own money, because I don't have that much money. Even less to invest.
It isn't really a high risk investment. There are no emotions coded in the bot, which could afffect the decisions if someone was manually trading.
