The most important technological advances coming are those that make it faster and easier for the average person to use cryptocurrency in their everyday lives. At the moment it is still a bridge too far for many people so they shy away. My good friend likes to say to everyone that no matter what they should still dip their toe in the water, get a wallet they can connect to their bank account, and then buy themselves some cryptocurrency (usually bitcoin). Be careful not fearful!
New wallets, new linked accounts to debit cards all of these will make a huge impact. We are getting there but we are not there yet.
