Sure, everyone's risk tolerance (and willingness to go through the hassle) is different. I only wanted to explain the possibility, not trying to persuade anyone :)

Also, for some people, it might be too much of a hassle now, but convenient at the next time when they would move their coins anyway, e.g. for a key rotation (provided that the blake2b price has not completely collapsed by then).

currently around $270 per coin (but fluctuating wildly). If you think (like me) that this fork has likely no future, it might be worth dumping them.

I don't think it is even close to worthwhile.

I wouldn't want to go through the effort and risk of bringing my sats out of deep cold storage, let alone accept the risk of making a big mistake while selling, potentially losing a significant chunk of sats.

And all of that to bump my stack by 0.36% (using dollar prices as proxy, ie. 270/75000) assuming I make zero mistakes, not even in a test transaction, along the way.

No thanks, I pass.
