Using lightning exactly like this the last year has helped me a lot with my on chain utxo set.

Being able to get away from an exchange in $5 chunks to a more self custodial option, even with the tradeoffs of lightning without my own LN node, and eventually moving on chain in a more planned way than doing lump sums or having a bunch of tiny utxo like I've done in the past.

Helped a lot with consistent DCA for me.
