I spent most of last week drenched in sweat, launching a vicious assault on Wall Street hedge funds which cost them $20 billion. Along with thousands of other ‘degenerates’, I bought shares in GameStop, a struggling videogame shop whose value has recently soared by 2,000 per cent. Behind the surge is an online community called WallStreetBets, where bored young men gamble on barely researched stock tips and crack tasteless jokes.
