It's easy to do an arbitrage chain a couple times, but people will start to get suspicious fast.

Suspicious? Sure, but will they care? He is dealing with Gringotts, or more specifically with specific goblins at Gringotts. They will be following their job specifications, probably their legal obligation, giving their company a profit and adhering to tradition. Gringotts wins, Harry wins, law is followed.

The people who lose are anyone who has invested in wizard cash (which is being inflated). But they aren't involved in the transaction and don't lose enough or rapidly enough that they would object before he has finished farming. In fact they only start experiencing negative effects once Harry starts spending.

In the early 1990s, gold was around $400/oz and silver was around $5/oz. Which is an 80:1 price difference. Considering that in the wizarding world, it is only 17:1, he can make about 4.5:1 each time. 5 times of doing that with 100 galleons will yield 180000 galleons, which he needs 60k of. Shouldn't be too much trouble.

It might be even better, considering the possibility that there might be more bounties he can collect.

What I'm more worried about are the implications on the Muggle side, and the fact it could endanger (even if lightly) the Statute of Secrecy. That is likely to draw political troubles from the wizarding world, and may be very well ruled illegal.
