The $50 deposit and rollover requirements you speak of is for Betonline not ACR.
For ACR you can withdraw without making a deposit this applies to methods like Crypto and Cheque.
If you are using ecoPayz as payment method to withdraw you will need to deposit at least once with your ecoPayz account. Minimum deposit amount is $10 minimum withdrawal amount is $10 as well.
You will need to verify your account if you have not done so already. This involves sending them a copy of your government issued identification like ID Card/Driver's Permit/Passport and an address verification document like Utility Bill/Tax Statement.
There is a 72 hour wait time from time of deposit to when you can request withdrawal. You will also need to rake 10% of deposit amount example if you deposit $10 you must play to generate $1 rake this can be done on any of the games Ring/SNG/MTT/Jackpot.
For me ecoPayz withdrawals are processed in 36-48 hours these days. For first withdrawal you should expect it to take a little longer than this.
If you need help you can use the help function on bottom right of the client or you can always contact the ACR Representative on Cardschat found in this thread
