Wait until fees on the bitcoin blockchain become higher again -- interest in Liquid network will jump.

This.

I’m now using the Liquid Network to stack L-BTC whilst the mempool is on fire.

Kraken Pro LN Withdraw > Boltz.Exchange LN<>L-BTC atomic swap > stacked sats secured by Jade HWW.

When, the mempool hits a quiet patch, I’ll swap back to LN via Boltz, then send funds on mainchain to cold storage.
