If you buy monero they will never know ;)

No

In the US, your tax liability is the moment you made a profit on any sale. You cannot take your current year's profits and buy something else and pretend you did not make any profit that year. Otherwise, you could keep doing that same thing over and over at the end of each year and never pay taxes on profits. (This is assuming I correctly understand what you are trying to do.)

E: Again, in the US, there is a reverse trick that the IRS is aware of. You take your stocks you took a loss on and dump them to claim a deduction, but immediately buy them all back within something like 30 days. This is called a Wash Sale and it resets as if you never sold them in the first place with regards to tax purposes.

Why tf are you doing this where you have to report it?

I'm not a real doctor. But sure, why not. Go for it!
