This is a great learning experience for my 11 yo son. He wanted me to buy him bitcoins because it was cool. Initially he wanted to put all his savings, I talked him into just a bit. He invested 13 €. He got the double. He wanted to invest all his savings again. I talked him into just a bit. He invested 30€,got 50€. He threw in 80€ (of a total of 137€ of savings) when the rate was 12k.He now lost almost half by, and learned a lot. About being careful, what a rate is, how money works (at his level). Now I hope that it will be 12k again so that he gets the money back :) But not something like 100k because I did not actually buy the bitcoins but merely acted as the bank...
