they claim they buy btc from some exchanges at cheap and sell the BTC to other exchanges at higher rate, its got a certain terminology which i cant remember...
This is known as arbitrage trading, but I can bet my hand if they are doing anything like this.
do u think they are reputable ?
Nope, absolute scam. Don't even bother. There are far better reputable bots you can use, though you need some technical knowledge to make it work according to your trading strategy.
Yeah, I think arbitrage was a thing of the past, maybe if we are still in 2017, I would believed that they can make money out of this system. But it's very different now, exchanges are well aware of this kind of trading and so they are not giving any chance for some to trade this way. Besides, it should be very fast that only bots can do it.
And so I agree that this could be scam, but I will say that the OP should stir away from any bots if he don't know how to even have a knowledge of basic trade.
well after committing to 10 days of staking my 9$ investment, they say i made 18.14 USD in profits, trying to withdraw, they wont allow it, it seems like a scam, glad i have put just 9$
