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
Your questions is not clear dude, but If I understand it correctly, you did buy a coin, lets say coin A and then the the coin suddenly drop, losing your investment. Then it not should be considered as trading because you didn't trade it, meaning buy or sell it at certain point. So its more likely that its a investment, if I'm not mistaken.
question is unclear !
if you lost your investment then you should not have invested all your money in 1 coin even if it is best project ..
next time diversify your investments .
That questions is not really clear, but we have to understand where the OP is coming from. It looks like he is new to trading or investing, and he still don't grasp the concept of diversifying his portfolio. But most of us did go to this experienced and I hope that he learns from this mistakes and next time we will try to buy other coins so he has some plan B. But yes, diversification is best suited in crypto as well. There are a lot of coins like Bitcoin and Ethereum and other altcoins that he can put is money with.
