But my main concern is how to lessen the capital gains hit I'm going to take if I sell within a year, it seems like there's no way around this if I don't hold my crypto for a year.
Since you say you have already made a number of trades in which you made a loss, you can use these losses (provided you have good records them) to offset some of your capital gains. If you have made capital losses elsewhere, such as the stock market, then again you can use these to offset your gains.
If you are married, then depending on both your income and your spouse's income, then it may make sense to file jointly with them, or to gift them some of your assets and file separately.
You would do well to take professional advice if you are talking about significant sums of money here.
