this will probably sound unbelievably lame but is there a quick and easy way to do it, maybe online?
Almost all major US stock brokers offer online trading and have since the 1990’s. I would imagine international brokers are similar.
I bet some made a bundle shorting the gaming stocks. (selling shorting – a short seller borrows the stock from the broker and sells it, expecting that it will decrease in value so that they can buy it back at a lower price and keep the difference).
And they banned online gambling.
