@mysearchisover Your answer: Lightning and POS.

Point of Sale? Is Lightning fully operational? I've read that Lighning might not be able to save Bitcoin.

POS = proof of stake, another potential. Lightning has been deployed on mainnet already. At the very least, it will solve the high TX fees and speed. http://lnstat.ideoflux.com/dashboard/db/lightning-network?refresh=5m&orgId=1
