A starter money maker is only ready if the output can be sold

A method can clear the visible checks on a new OSRS account and still leave you with items you cannot turn into coins yet. That is a different problem from having too little GP to buy the first batch.

Consider a fresh free-to-play account. Its Fishing level might qualify for a gathering method, and gathering may require no GE input at all. But new-account trade restrictions can prevent certain outputs from being sold on the Grand Exchange. A quoted GP-per-hour rate assumes the output can actually be sold. If the sale is blocked, the stack in your bank is not cash for your next run.

The early-game OSRS money-making finder separates methods by stats, available cash and access. It also says plainly that quests, items, gear and new-account trade restrictions need an in-game check. A public Hiscores lookup cannot settle those questions.

Before doing a long session, check the specific output against your account's current trade restriction in game. Gather or make a tiny batch, attempt the sale, and count only completed coins as money you can spend. If the sale is unavailable, choose a different route or work toward lifting the restriction. Do not scale the method based on an estimate alone.

The OSRS Wiki account guide describes new-account restrictions and examples of affected items. Its item list can change, so the in-game check is the final test.
