I think my luck is very bad. I can not earn good profits on cryptocurrency trading any day. An example of this is Doge coin. I invested in Doge coin probably 2 months ago. Which I bought 39 satoshi and bought a total of 126000 doge coins. It was almost 2-3 weeks, I did not check the price. But when I check price on coinmarketcap a few days ago, see Doge coin 100 satoshi cross. After that I was very happy. But when I login into exchange, for selling Doge coin, I was shocked, seeing that my coins were sold in 49 satoshi. I did not remember when I had a sell order. After seeing that I was upset. That was not the first time, before several times, I could not sell many coins at a good price 😞
Luck has nothing to do with it. And besides, it look like you have profited already why are you mad? Sometimes its boils down to timing, and a good advise is to have your entry and exit plan in place. If you set that in motion, specially the exit plan, you should have made a profit, but at the end of the day a profit is still a profit so you don't have to feel mad or something.
But finally, an education has realized that if you buy a coin for long or short time, then you should check price minimum one time every day.
Let that be a lesson learned for you, at least check the price and see if you hit your exit plan then all you have to do is push the sell button.
