Our company works in the crypto space and we have a small research area that includes trading. We played with arbitrage strategies and have not seen a consistent return. Most times when you calculate a high return path it is because some exchange is not working really well (e.g. delaying transactions). Not saying that our observation is universal but I don't believe you can make right now a lot of money with arbitrage except in very discrete opportunities.
BTW, highly recommend the CCXT library[1] to connect with multiple exchanges.
