Hey Luc, Thank you for your videos, I am learning alot about cryptotrading.

How do you do your trades? Do you stick to the pair or do you switch between coins?
For example if you buy Ethereum with bitcoin do you then sell it back to bitcoin at a profit or will you trade it to something else (like USD)?

I have noticed on some of the coins that I have in my portfolio that I bought with bitcoin that the value of bitcoin keeps going down but up against USD so it made me think that perhaps I could sell the coin to USD instead of waiting for the price of bitcoin to go up higher than I bought to make a profit.
The problem is to know by doing this how do I know selling it this way its at a profit?
So I was wondering if you do this and if yes do you have some sort of strategy in place that ensures you are getting a profit?
