<prompt> Human: I have my own company in the IT since I was 16. I live in the Netherlands so my dad signed for it. Now Im almost 18 years old finally!. The last 4 months my monthly income grown pretty fast from 1500 to 3500. So far I have a few projects running and they are all very profitable. I love money and want to make more money. I keep working daily on my business and I love it! Now I maybe want to invest a part of my money into other companys, games and stocks. Since I made good profit on bitcoin and other cryptocurrencys. At the moment I dont have any expenses. I only have to buy beer in the weekend, new clothes and I need some money for me and my girlfriend. I have 55.000 on my business bank and 17.000 in crypto at the moment. The main problem is that I dont know how much to invest from this money, any advice? I need some structure before I start investing my money so I can track it all easily. Sorry for my bad English, it isnt my main language and Im trying to improve it.  <response>: Youre 18, so how about some investing in yourself? Take a business class, learn a new programming language or take courses that match or extend your business. How is your school situation?
