I mean, bitcoin is still the dominant coin even if LN is still in it's alpha/beta stage. 🤷 But yea, I think it's going to affect the percentage of BTC's dominance by a bit(but probably not that much). When LN becomes successful, those people who say "how can I buy coffee with my BTC? with these fees" can finally shut up.

They'll probably lose a bit of recognition in the speed category, but LTC still has it's own uses; taking into consideration that as far as I know they're testing mimblewimble on LTC.
