My 18 year old son recently was given his child trust fund valued at just over £20k. He’s reinvested it into the stock market and started a dropshipping business, my son really is good at making money through these things and has recently made around £240k he insists on spending the money on a Tesla Model S but I really don’t want him to spend his money on these materialistic things, we’ve had arguments due to this, he’s even been abusive and hit me when I’ve put a cap on his bank account but he keeps on spending, I really don’t know what to do
money is changing my son and it’s not at all for the better.
