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 ?
Npor, 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 startegy.
