Just in the last couple of days there's been some BTC 30 going out (and another BTC 10 still in the wallet) so it's a fairly likely that Dr-Exchanger both has the funds and their user account hasn't been hacked.
$ 50,000 works out to be ~ BTC 77 while $ 1,000 is around BTC 1.534 - all the recent outgoings are above this BTC 1.534 amount.
Actually have to say its very nice reasonable analysis
