Best strategy to swap all ALTs to BTC without facing losses?

I'm looking to only hold BTC after this/next year. What would be the best strategy to do this without facing any losses? I have the following strategies in mind. But please feel free to let me know your ideas/suggestions as well.

1. Swap all ALTs in profit immediately to BTC regardless of BTC price.

2. Swap all ALTs in profit to stablecoins to buy BTC in the next bear market/dip.

3. Swap 50% of each ALT in profit to BTC and swap the other 50% to stablecoins to buy BTC in the next bear market/dip.

TIA!
