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?.
Final aim is to get more profit in USD dollar but for this I need to gain more profit in bitcoin you know. So when price is low, I mostly concentrate on when to sell bitcoin and how soon will I see low price to buy even more bitcoins, then I repeat the same process, mostly successfully but it's still hard decision for me. For example when price was 13K last year (in summer), I immediately sold my bitcoin and when price felt on 9K, I bought them back. I know it wasn't a good time cause we saw further fall but I am still satisfied with the result. Now I have even more bitcoins and waiting further rise to sell them and profit.
