Should I DCA with lightning?

Hello All,

I have been DCA-ing around 60-ish bucks every month on the main chain [I have my own private address] and I recently learnt that having so many transactions can lead to UTXO fragmentation which can lead to higher fees in the future.

Apparently, one of the solutions could be to DCA onto the lightning network and then later swap it with the main chain periodically. Do you think its a good idea? or is there a catch that I am not aware of?

I plan to hold to hold it long term. Thanks!
