If I lost most of my capital in one coin, I will hold the first to coin it up again, whether it can be called trading or not?
Give your opinion

If you are buying a coin in any of the exchange platform, don't just buy quickly. You must supposed to do some research first about the background of the coins, if it is potential or not, check if the volume in the platform is high, check if there are a huge traders to that coins too.
In that way you can see if it is worth to hold or not.
