This step indicates the importance of regulating and monitoring digital asset activities for tax purposes, this might not shock US taxpayers, but they specifically call all taxpayers, I am not from the US, and I never filed such a form, so I don't know much but is there a chance that there are some people excluded from the category of taxpayers legally or illegally. Because they are using the word taxpayers, which excludes those who don't pay the tax. Other than this, there is a slight difference among the questions being asked on four different forms.
Like in the question of 2022, all the words are same, only the word gift was not included in 2023 while included in 2022's question. To me, the question of 2023 and 2021 looks almost same but a little difference of virtual currency and digital assets, I doubt it changes much or is it?
