> You've missed step 0 (and earlier): how did you trustlessly obtain the bitcoin in the first place? Your options aren't good here: You're missing an easy and obvious option. You plan to buy 10 Bitcoin (not saying it's a good idea): you wire tx enough to buy one on Gemini or Coinbase (or whatever exchange fits you), wait for the tx to clear, buy one Bitcoin, move it to your hardware wallet. Rinse and repeat 9 more times. At any one time you're never exposed to more than 1/10th of the amount you planned to buy. I think a lot of highly speculative investors but still cautious people proceeded that way. There are even sites tracking the Bitcoin and Ethereum and whatnots addresses accumulating coins on a regular basis.
