I dunno - he could have consolidated when fees dropped to 30sats/vB like many did.

This is a reminder that your Bitcoin activities are on you. You're the one left with the outcome.

Withdrawing your DCA immediately from the exchange was probably not the best strategy.

Assuming that fees were always going up in Bitcoin terms, also not the best assumption.

Think for yourself & don't get caught out blindly following the advice of an OP. Rushing these things doesn't tend to work out well.
