Thank you so much Luc for these amaaazing videos!! I think I am able to spot the bases pretty accurately now but have some confusion around understanding the profits.

 For example, if I see that there is a base crack for STEEM/ETH, I can buy STEEM using ETH and sell it when it eventually comes back to base or goes over it. but what if the price of ETH also goes down and up during that same period? wouldn't that affect the profit margins as well or am I missing something very obvious here?

Thanks!
