Selling as a tax loss harvest, immediately rebuying

Has anyone done this? Thinking of doing this for the tax savings since Bitcoin is a long term hold for me, the tax loss harvest could benefit me in the short term allowing me to take profits without paying taxes on gains in stocks.

Round trip fees and spreads obviously comes with a cost and from what I have read/heard the legislature could change wash sale rules regarding bitcoin. Main risk here that I see is if legislature does change and it is retroactive for this tax year then I wasted money on fees and spreads for no reason.

Has anyone done this, any insights or logistic advice for doing it?

I used river before so I would probably just use river again even though the fees are not best just because it is all set up for me to do it there and I’m familiar.

Thanks in advance for your comments!
