You say that anyone operating with BTC/USD has made a loss. This would suggest that CAT hasn't performed well on any of the coins which have fallen by a similar amount over the past few months.
No, i told
"In the USD/BTC of course, all people who hold have a loss" which means "if you hold your BTC while market (USD/BTC) is crashing, of course you will have a loss"
yea, sadly true!
CAT has no Exit Strategie(Cat has no strategies at all), only "sell all"(stop loss)l Parameter, chosable by the user.
Cat only is sucssfull at a rising or floating around Market.
What other Exit Strategies do you know?
Find me a trader who is able to make Gain on a dropping market (or even a human).
There mathematikal Algos using some Statistik Grid maths to try the best Exit without loose.
But i have not as you have no such Algo ..
Don't take me wrong, Cat is nice, but it is not a autark Bot or something this.
You have to think and trade yourself, just using CAt as a real supporting and helpfulll Tool as well.
When a market is dropping Sell(Ping) -> Buy (Pong) works (you will have more Quantity in Alt-Currency)sorry that is not a real gain

I have a lot worthless Altcoins, cant sell them for the BTC what they have cost me!
And also on Cat you cant realy use Sell and Buy at the same time, not even as Exit Strategie while you sleep or something else.
