Just thinking if there is a way to manage multiple whatsapp accounts from one device, it could be my smartphone or in a computer. I tried a couple of app, they can duplicate whatsapp quite easy, but it can duplicate only one, and what i need it is at least more than 20 accounts. I think that if it is easy of duplicate one whatsapp, why can’t i do it with 10? Must exist some program that do this. 
You can only run up to 2 apps of whatsapp
Check out xdadev and xposed forums, i’m 90% sure there was a module for multiple whatsapp/instagram apps 
Why not just use Memu?
Because he wants to use those apps on his phone.
Well then try using Memu on laptop and then use RDC to access laptop from your phone
It is really possible to run multiple instances of whatsapp app on MEMU simultaneously?
Don’t know but you can run multiple instances of Memu
I think running many programs at same time will drain too much ram and processor capacity.
These clone softwares can make a copy of whatsapp easy, you can for example download 2 ou three clone app and duplicate 1 whatsapp with each one. I am looking for a program that crack this funcionality and open for more copies in same space. There must be. If there isn’t, its a good chance for a programmer make money.
I don’t understand why you need so many Whatsapp instances in one device? Spamming the shit outta people?
Anyways, if you will be using more than 1 instance of any social app including Whatsapp, you are risking to be suspended/banned by that social network, because they know your Device ID. No one is running 2 whatsapp apps from one device…
I can run a software that do this in a computer or a remote server too, it does not make any difference for me, I just want to manage all in the same place, like an email colletor.
I just take advantage of the “2 free ad per user” on a local sales website from my country, i can make 1 acc per number and i can not add other contact, because if i do, i get ban. So i put “contact by email or whatsapp only” .
People can work it out as long as it popup in mind. There does exist a program called marketerbrowser that will be able to configure each account with a unique browser fingerprint without limit.http://www.marketerbrowser.com/
