The future is here coaches.
Lately I met many coaches and their way of playing which consisted of creating several accounts (one main and one secondary account) but different teams to be prepared if they find a gym that is already full (from the main account) and then use the secondary account to unlock a space and thus win your coins.
And then I discovered the new equipment:
Green team: Yellow and blue player.
Violet team: blue and red player.
Orange team: Red and yellow player
Honestly, I do not like this but it seems that Niantic is not worried about controlling the amount of accounts allowed (1 account per person)
I clarify that I currently have 3 accounts of the same team, but I only use one, since I do not see the meaning of playing with several accounts.
