I'm so stupid when attending crypto currency, who can help me to get money back? I also ask many traders who has experiences in this one, but I still lost money
You should be calm about this situation. Many people have entered the Crypto market with the desire to make a profit from speculation.
They always have a lot of capital losses because they have no knowledge of speculation and always listen to the crowd. That is the biggest mistake that newbie often make.
I recommend learning more before proceeding to invest in any altcoin.
