Few days ago I decided to utilize some fraction of bitcoin just sitting in my trading wallet to try profiting from the market. Although I may profit when the profits was calculated in dollars but unknowingly I lost massively in Satoshi value. That means assuming I just kept hold of my coins I would had made almost the same value I made with the coins i bought. Many traders haven't realized this yet but just get carried away with the US value of their trades without realizing they lost some satosh in the process. When training, what are you mostly concerned about, to gain more profit in bitcoin or gain more in usd dollar without minding if you lost some Satoshi value?.
Looks like you learn something while you are on progress. Good thing you have realized that.
However, different traders have different goals and purposes. Different strategies also apply.
There are advantages why traders sometimes opt to sell when they see gains in USD value, they are playing with the price. Maybe out of their analysis, it seems a good move. Proper execution is the key to gain profits in the market. You can also try other trading pairs.
