There are some preliminary findings which we are trying to confirm.
Related to security issues in your app or OP simply getting his API keys compromised by something that was his entirely responsibility (e.g malware in his device, phishing, etc...). I'm not trying to spread any FUD, but if there is any possibility of your app being vulnerable in anyway, you need to disclose it.
I myself have used your app for quite some time and only stopped recently because you do not support my favorite local exchange, but I still have the app installed in my phone. I don't want to risky anything because of a possible issue on your part. =/
Now, if the issue is on your hands, OP, I can't see why TabTrader would return anything to you. Electrum or Bitcoin Core don't reimburse people if they get hacked or download a fake wallet.
Thanks for participating
I did not download a fake wallet but rather from the official website that referred me to the Google Store
If the problem from me , how do I buy at a high price and sell at a cheap price?
Does this do sane?
I have done all the protection measures in my phone and I have been dealing for years with other sites and applications, and I have not been exposed to such before
How do you want me to lose something I have no reason for.
