Like every L2, it depends on your use case, eg when mainchain fees were high in May, many used Liquid to stack sats for 99% fee savings and to hodl in the short to mid-term. Once fees were sufficiently low again, you could peg back into mainchain and hodl long-term.

Same with Lightning channel rebalancing via submarine swaps from Lightning to Liquid. Boltz integrated Liquid for its users for this very reason (cheap fees, highly compatible with Bitcoin, etc.) and it's been quite in demand.
