Bitinka is scam. I made withdrawal of 2.52 ETH on 11 Feb, waited 72 hours as was advised by FAQ and submitted ticket on 14 Feb. Later my account was blocked, I can not login. I emailed to support but do have any answer what happened to my account and withdrawal request. I only have some autoanswer in Spanish "
