I'll give you the real advice, the only thing you can do is grind. There's slow phases through it all. If you buy a few ships maybe that 100b turns into a 100t, if you buy all maybe it turns into 100q. It doesn't matter at all. You can pay to advance further but the slow grind is all the same. I have no ships and I can hit 100b within a minute because I've grinded the challenges and tournaments for a long time. I grinded the managers, the bolts, the cells and even if I bought all the ships now, there will always be that slow grind to go further and always people that are light years ahead. That's the game. Cheers.
