Other ATA games have a bank :? It's not fair BB are a ripoff...there was a reason it was 900m but it refunded 600m -.- they're not useful to me I'm never going to use BB
Banking your money would ruin farming, and you can already bank money into bronze bars or make an alt, and grow it. Allies work as well but if they're inactive sometimes they leave the game, making you lose money. Thats why I prefer alts
Stop worrying about banking your money without cost. This is not banco popular or the world bank (not that they take individual deposits, but the name sound good). Just. Play. The. Game.
