user35896: How can I set a permanent address wallets to send and receive?
How can I find out in advance which address the coins will be sent?
 We have a community in MLM that pays membership of the coins.
Upon registration, it is necessary to specify the address of BTC wallets. Payment system detects on the basis of registered wallet in the system. Now we have a problem because sending address changed every time..so that it shows in every transaction a different address.
You can help solve this problem?
Thank you in advance.

user35812: If you are asking how to identify which payment came from who, then you want a new receiving address to be generated for each new member.
With an HD wallet you will have control of all address balances despite the address changes
