Bluestacks is the best emulator.Just use multi instance on my apps screen.
You must have a good machine to run 4-5 accounts.
With i3 8100 and 16gb ram i have no problem running up to 10 instances.
I have a decent enough computer which will easily handle the load of my 5 teams. I wasnt sure what multi instance was so I didnt use it until I got more info on it.
Cheers
Some of you look back and remember how it was while some of us look forward to see what it could become
