I am trading with smaller amounts on yobit but I am unsure why there is difference for human and bot traders. I think there must be some kind of minimum trade (not minimum order) limit for bots so eventually it might be as equal as human trades. In other words bots can choose frequencies but overall minimum limit should be 10,000 satoshis per lot (and bot can be set even to place order with 1 satoshi). I'm not sure though.
I think that Human and bots should be given the same rules to trade on Yobit. A lot of times bot place a lot of very small orders giving the wrong impression that there are too many buy and sell of the coin.
Since bot is auto and not human, it should have some restriction like maximum orders etc.
the same rules apply for both human and bots the same way.
if you have ever tried any API or even YOBIT API you would have known this, when you send an API request to open an order on YOBIT or any other exchange site the same rules apply meaning if you place a 1 satoshi order it will be rejected and you will receive an error as your response.
