Yes i lost too much money with trading. In 2018 is the worst year for crypto i think. But at least we learnt too many things about crypto and trading. This is not the end. We can start again with full of our experiences. But you are right. Trading and holding caused too much loss this year.
This year has giving us so much loses because of the crypto value that is has been down until this month. I even lose this year with the coin I hold the price went down. I believe we will see again a bounce back of cryptocurrency maybe next year.
