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
For me it is understandable to lost money when you are newbie in trading I was experience the same before but far less amount than what you have loss. I suggest buy only coins that are in top 10 in coin market cap dont invest in speculative coins it is very risky. just be patience if you keep buying and selling when it going down your investment will go no where 
In the second thing, that amount should manage by experience people to avoid loss in the whole amount. You can be people who manage but you need to get your experience first before doing trade.
