This doesn't make sense to me as I would have assumed that over time more people would coming into the BF trading world year-on-year, especially from the 2018-present boom in matched betting. I would have thought that there would be a lot more people looking for ways to make an income online in general and that many punters would have wisened up to how the exchange/trading offers better value.
Could it be that 10 years ago the casual punter with ladders could easily pick up an edge from the markets with enough money to go around all the software traders more evenly... which lead to many happy people coming online to discuss and set up challenges? As opposed to now when only the well-practiced traders and bots are taking most of the money from the markets? Thus any newbie doesn't stand much of a chance to last long enough and participate in a forum community? I'm not so sure that explains it though as profitability always feels like it's just round the corner and people like me will keep trying again and again as well as coming on here to try and learn more.
Alternatively people did get smarter and realised that they have nothing to gain by posting but everything to gain by reading the forum

Obviously there are still people making a lot of money from this but it sort of feels like a dying, or at least less active industry than 5-10 years ago
