Bitcoin adoption will probably continue to increase if there are not many Bitcoin haters who appear every year, because investors and traders who especially like Bitcoin will definitely continue to use Bitcoin to invest and trade so that new people will definitely see it. This is a trigger to adopt it in the future, especially if now there are several large companies that are starting to accept Bitcoin as payment so that the good effects will probably continue to be in Bitcoin in the future without having to wait three years.
