Hi Birhanu,
AvaTrade is still existing and doing very well.
AvaTrade is a broker and provides you the tools to trade on the market, but the trading is done by each individual itself. I'm sorry that you've lost money with trading, but I'm sure it wasn't AvaTrade's fault as everyone is responsible for their own money and actions. I must also say that I don't know when and what you traded and on which platform, so quiet frankly it's hard for me to judge.
As I wrote in my post, I'm looking for IBs who're interested in bringing us Traders and to get a referral commission for that. You know anyone?
Have a wonderful day!
