Not following the mempool transactions super closely but it doesn’t quite look like the ordtard business, more like a lot of utxo consolidation. I assume they’ll come down but not to casual everyday 1 sat/vb status like the good old days
As for DCA’ing on an exchange, it’s still fine in my book to withdraw every million sats or so. I only do free withdrawal options on strike and cash app, yes they take a while but still get to self custody within 12 hrs or so at zero cost to me
