It is supposed that a new fork is coming up soon in december after the november fork.
By now, Bitcoin is already leading in price. I couldn't suggest anyone to buy bitcoin at the moment.
There are speculations that bitcoin price will crash after fork. It is now upto you whether you buy or wait.
Thats true its really hard to predict the market now but i highly suggest if your goal is for long term then dont be afraid to buy more bitcoin. Bitcoin really well in the future for sure so better to start buying today.
