Do people realize the IRS doesn’t mess around?

I think a lot of people think that since they don’t get a bill from the IRS that they are in the clear from past trades and gains. I am self employed construction worker so I know first hand they are ruthless and will find your past trades and not only tax you but add penalties and interest. I see YouTubers recommending to trade btc or eth for this other project that will pump but once you trade an asset for another that is a taxable event when you had gains on the original crypto that you traded. Just please everyone don’t mess with the IRS, If I didn’t have my back tax issues I know I would be trading and think they will never know but they will find out eventually
