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?
That's a very good question. There aren't many forks these days because first of all, it should have a reason. When you make a fork, what change do you make? You have to make a significant change for the betterment. Besides significant change, you have to gain the support of the people and the developers, which is the hardest job. Your fork needs to gain support, the attention of people, it needs to become popular. How possible is that? Especially when Bitcoin is the number one crypto currency with significantly higher market cap then the other altcoins? Even the 2nd one? Also, how many successful Bitcoin forks do we know? BCH? And look at critics of BCH too. BSV is a scam token ranked at 112th on coinmarketcap.
If you want it - you need a capital and expertise from around any sphere, basically, and people usually don't have such capital (fortunately or not, that's a good question too
).
