The advantage is the lower fee and faster transaction times without the complicated (and sometimes, impossible) set up process needed for Bitcoin Lightening. And believe me, I've tried. The two LN wallets on Fdroid right now are buggy and nonfunctional.

Bitcoin and Lightening won't gain widespread adoption if the transactions remain costly and slow, OR if LN remains nearly impossible to set up.

#[3] I'm not a BCH promoter. I'm fine with any crypto that could compete with fiat in speed. I actually use LTC more for that reason 🤷‍♂️
