This is amazing, stop to trading on bter.com they are scammers.
''Also in BTER it was supposed to receive more often the batch payment but this is not happening and their support sucks.
I think that until now they could make some small payment from the fees that they charge!''
Yea, their support is bad.
I have stopped there to trade but even though after the hack I traded small amounts after because I trusted them but hopefully I didn't get scammed again.
What i was able to understand is that they give you 1% bonus of the coins you deposit but they also deduct 1% on withdraw which is unfair too.
From your words, I infer that you get a bonus when you send funds to your account at Bter and get it subtracted if you decide to withdraw the funds. How is that unfair? Indeed, if you earn something (or big time, for that matter), and they subtract the same percentage (i.e. more in absolute terms), this is only marginally fair, but could you confirm they are doing exactly that and not just take back the bonus you received (in absolute terms)?
I've long stopped trading there so I don't know (but curious to find out)
This is the effect of this marketing because you think that you are getting 1% bonus only by sending the coins there.
But lets say you deposit 1
BTC and you get 1% bonus and now you have on your balance 1.01
BTC, but when you withdraw 1.01
BTC - 1% = 0.99
BTC.
You see the difference?
This is exactly what I've been asking. This means that the exchange is using relative values (percentages) in calculating the bonus. In fact, I think you are confusing something since if you, for example, deposited 1 BTC, got 0.01 BTC as a bonus, earned through trading 8.99 BTC (so your total is 10 BTC), and then decided to withdraw the funds, they would deduct 0.1 BTC (1% of 10 BTC), which is nonsense...
If what you say is nevertheless true, such marketing tactics would be a masochistic exercise in stupidity
Firstly you are guaranteed that you will lose some money whatever if you got any profit from trading there or not.
So this tactic is smart from them but for users it not good because it's not good, we are not fools.
