I agree the password thing is the only problem i see in terms of potential headwinds. There will be a work around somewhere, and i think we will see the need for total and absolute security come to the for front in the next phase for crypto. I see it tieing in with a general need by every day internet users for online security and data security system/s that will be developed. Decentralised data storage/privacy can and will come to the rescue and by that point people will be accustomed to it as everyday internet users. The more and more companies that are hacked and have to pay with money/bitcoin for their data back the more it will happen, thus driving these security developments to where they need to go.
