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 😞
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.
Always check the market before you sold your coins because every second it changes the price it's up and down so better check it. But of course no one can know that sometimes the price is more than to what we expected.
