Untrustworthy
Did earn to learn, first surprise was it was the first time the reward is locked. So it nearly went to 0 until it was possible to unlock, then you have high fees to convert it or to send it, it also take ages so it's not possible to withdraw it unless you add money. Sent 2 tickets, no answer, asked on tweets no answer, reviewed on appstore got answer. Seems they care more about their image rather than customers.
