I am 16 to and from Europe. I have trade with the money of my dad 1 year ago. it was more a invest but it worked. I put 5500 Euro in BioNTech and got 300% after a year. But in this time I was greedie and the stock market was like a drug for me. I put another 1k in GameStop as they hit 200 Euro. And… I hate me for that trade. I lost 1k of the money of my dad. But it did not hurt that much because I have got mich money from the BioNTech trade. 3months ago I took some money from BioNTech (7k after taxes) and tried to trade with options and Knock-out Zertifikaten. And yeah I lost another 1400€. Now I am done for the first done with stocks because I felt like I would loose all the money of BioNTech .
