I'm not sure why you are on coinspot or what you are actually trading...
This is Bettrex , those gains are in the last 24 hours & apart from the big pump at 1000% return, the 40% to 80% are a daily occurrence, weekends get real crazy with trending coins having $300 k on each pip bidding & selling. Polonex is just as good with Kerkan being the leader of volume but not as much choice as the other two
