What you just wrote is precisely why the ones that are being sold are not the ones that the developers would actually use. One you start listing an item on the market, you're opening it up to heavy saturation. The profits will either be very minimal, or they will be very quickly.
The opportunity to scam someone is always there, as well, but this happens in nearly every situation.
I'm aware for the possibility of a scam that's why I wanted to post here to verify before I jump the gun. So you think there's a high chance that they keep good version for themselves and sell dysfunctional bots to the users that only show a fraction of the real arbitrage opportunities? It's definitely possible. Is it viable then to develop my own program and assemble a team in order to scout for opportunities on all the exchange sites, as a hand-developed bot would be legit? And since the concept of arb is legit it should work out overall.
Risk by holding a bag in which you cannot sell anymore in profit due to the lag in the market price changes.
I'm assuming you mean that the prices change while during a cycle? That's one of the things I was slightly confused about. If the bot starts a cycle and isn't able to complete it, would it simply try to revert back to the original currency, or does it continue the cycle at a loss. I'm also not sure if it's the bot that performs the transaction, or rather it simply alerts me of the opportunity and I have to do the cycle myself. Thanks for your offer for help.
