Bitcoin will become like digital gold.It is unlikely to be used as a daily payment due to its high transactions.
I disagree with this. For a week now I have had this site running
https://www.lightningslotmachine.com/, I have already paid out 200 transactions using lightning and received even more.
All transactions has been instant, many with no fees at all.
Still very new and still in beta, lightning already works quite well as a instant payment system with virtually no fees.
