Starter Band

Every merge combines two identical items into one item a tier higher, so reaching this band takes roughly 1 starter bombs worth of material — about 0 doublings from the bottom. That is why raising your spawn tier matters more than collecting more low-tier bombs: it moves your starting point up the exponent.

Cash per second for this band is estimated at roughly 1–8. The game does not publish an official income table, so use that range to compare bands against each other, not as a literal in-game figure.
