Bitcoin doesn't, bitcoin investors do. And until you can pay your Snickers at a grocery store with bitcoin, that won't change.
You won't be able to buy snickers everywhere in BTC, but we are slowly getting there.. The number of things I can buy with crypto is increasing significantly (now I pay for VPN, web hosting, domain nane, consulting, ... in crypto). In addition, probably firsties are not aware, but P2P networks without KYC are exploding everywhere. I can get cash for crypto in under one hour where I am. You can today go to a number of touristy countries and live of exchanging BTC for cash securely and with 0 identification. If this is not big enough then I don't know whay would be.
