Cardano (ADA), EOS, bcash (BCH), ripple (XRP) and tron (TRX) are shitcoins being traded on bitmex.
This is not what can be considered a "shitcoin" as a TRADER. (no offense)
You might be right when it comes to the intention or execution of the mentioned projects (really don't want to discuss this here!

).
But, when it comes to trading, everything that matters is volume / liquidity.
Is any of those coins easy to manipulate because of low daily volume? No.
Is there a chance any of those coins can go to zero in a small time frame? YES! But, unfortunately, Bitcoin has the same probability to do so.So basically, calling those coins "shitcoins" only is your personal opinion (no offense) but has nothing to do with a trader's point of view.
Together with the illogical way of thinking he is trying to defend and the 'test investment' of 500$ (initially 1000$; which could very well also bee 100$ or 50$, since it is a test after all) it raises red flags.
I agree. There should be no price for the bot at all - commissions should be enough.
Also, there should be no "minimum investment". Any balance should be fine.
