I've been following the crypto game for a while now and enjoyed some pretty nice arb opportunities back in the early bitcoin days, but what i can tell you now is that these opportunities are gone and the prices are now all aligned because of the proliferation of bots and arbitragers
The only price differences you see today are always here for one reason; the exchange is either a total scam; wallets are disabled or volatility / risk is extreme and arbitrage doesn't make any sense
It is a waste of your time and money imo pursuing that endeavour, as it is now becoming exclusively reserved to well funded and staffed professionals who can deploy low latency bots with very sophisticated strategies
