First of all:  I personnaly lost 2BTCs - mostly earnings - on whaleclub.
I'll definitely avoid similar experience again.

The platform looks promising, fees are quite low and there are some markets I'd like to play with.
I've sent a email to support to explain my doubts.

Now, it's incredibly difficult to find any information about them. Who are the CEO/CFO/CTO ?
Anything I've found is either black (like some trashing thread on bitcointalk), or completely white (all those guys hoping you'll click on their referal link....)

No gray area, found nothing about scamed poeple on twitter or over the web.
I mean... Does any one has heard about some guy who's already been scamed?

The first argument coming from support is the "Covesting" partnership (and this paternship seems legit)
Apparently, Covesting is fully leggit too. I've never heard of them before, can't say if it's for real.

The second argument: I've found few technical details on the platform that let me think I'm facing something close to Whaleclub.co back then...
I've exposed those to support and will eventually get some feedback for all of them.

No order books seems reaaaally odd to me. (just like whaleclub). Support replied:
At the moment we are updating and improving the order book Widget to include aggregated liquidity. The widget for the order book will be added back and available for all users in one of the nearest updates.
Our liquidity aggregation system collects the pricings from several exchanges and combines them into one deep order book, providing tighter spreads, better entry pricing and liquidity. We employ a STP (straight through processing) system as well, if that is of importance to you.

Okay, seems legit, will wait for orderbook.

Liquidation funds. Nothing about that on the patform anywhere... Support replied:
In regards to position liquidation: liquidation may occur should your available margin drop below 0%. Before liquidation you will also receive a margin call prompting you to increase available margin in your trading account.

Okay, I'd like too dig up this point in my next email.

Some other technical detail I won't expose here make me concerned about this platform.
Sent an email yesterday, no response yet.

Neutral argument: Support replies sloooooooooowly. Like, Zootopia's sloth slow.
That's neither positive or negative. Just a piece of information.
I'd say those guy are working so hard getting those conversion numbers up they might forget actual customer support...
But I'm an entrepreneur myself, and that's the way I think. 

You could imagine guys are waiting for amount to be big enough to exit scam,
but regarding all the efforts spent on marketing, I can't imagine those guys just "waiting for an exit".


In conclusion
I'll keep watching the platform and eventually invest small amount. Looking at the market right now, won't be hard to take some profit.
The goal is to bee able to get any "substantial" amount (like 1BTC) to see how withdraw behave.
