Sad to hear that. It was for the best that he learns though. Take it as a learning lesson is the most important thing with any losses in crypto. I hope he gets his BTC back. I have made millions and lost millions of dollars trading crypto, could have had maybe double what I have now in my crypto portfolio if I had done things differently. However with that said I thank god everyday because I could still have nothing. I also would not have gained the knowledge I have now if I had not made those choices and lost that money. The lessons / knowledge I have gained along the way trading and watching the crypto markets the past 5 years has taught me many things. The right knowledge is worth more than any amount of money as it can be used to make you more.
