When you read old threads, you will hear of many soft forks and including a few hard forks that gave birth to Bitcoin Cash , Bitcoin gold, Bitcoin SV. The last one should be BSV in 2018.
What happened differently that there are no threats or signs of forking?
Generally, investors are currently not looking to invest in any altcoin/shitcoin other than Bitcoin, which is why the popularity of forks of Bitcoin and other altcoins is gradually decreasing.
Moreover, if you invest in altcoins, you will not get profit even after holding that investment for a long time, as you can get by investing in Bitcoin. Since if you invest in other coins, you will not get profit even after holding that investment for a long time, but rather the total capital will be exhausted, so why would people make those unnecessary investments? That is why altcoin/shitcoin/memecoin/forks investors lose interest.
