I don't know about that. There are plenty of people on r/wallstreetbets that have made an absolute fortune shorting the S&P500 right now.
I'm sure loads of people made loads of money and equally these people lost loads of money at other times and you don't hear from them.
I've posted on reddit before , its important to remember about forums that there is so many people posting stuff they have no clue about as fact. I try to remind myself of this often . People just post stuff like its gospel , I was a moderator on one large gambling forum and we had constant problems with people "after-timing" , there was endless people turning up with stories of how they are making a fortune . There was a winning screenshots section that was littered with huge wins and you only had to look at what these people where doing to realise that they where in fact clueless and wouldn't be long losing it again. Whenever we ran competitions and people had to post their bets before the off you would see that over the course of a month there was almost nobody probably less than 1% making profits.
There was always the guys that "didn't want to give away their edge " that would be offered to post up a screenshot of net deposits v withdrawals and they would quickly disappear.
And fair play to Colm and Brendan posting Bitcoin and Tesla bets , I've more respect for anyone who posts prior than people that pop up afterwards with the fortunes they made.
