What are the hurdles to making cryptocurrency part of traditional economies?

I think a basic fear of the unknown will continue to be a major hurdle. 

I compare this to the same type of pushback I received for years about migrating systems and services to the cloud. A general lack of understanding -- plus a lack of desire to understand, as well as plain old fear -- caused a massive lag for many such migrations. I'm still only halfway there...

The hurdles come from the immaturity of the cryptocurrency ecosystem, with its huge volatility, lack of transparency and "figure it out as we go" nature, but I think the main thing here is ultimately governments' not willing to let go of their authorities of financial infrastructure systems. The current way of set up for most developed counties are that governments facilitate the role of central banks in the economy. Even central banks are involved in making money policy, governments are ultimately responsible for the regulation of it - how money is created and distributed, via banks and financial institutions. And let's not forget governments rely on taxes which replies on the above systems. The fundamental principle of Cryptocurrency challenges and bypasses the above systems - have we ever seen any authorities willing to let go of their power without seeing any significant upside to them?

I am not convinced that the “old school “ banking or investing community is ready for this. Nor do I believe it’s proves it’s value. Once you can actually use it in a day-to-day environment it may gain traction….just not yet

99% of all exiting crypto seems to be created from the start as an intentioned  rug pull serving  no purpose other than to enrich a few people who get in early and get out before the collapse.  NFT's are the same thing.  Even the crypto coin banks are  built on a house of cards.  Government is interested  in  digital currency  to plug the holes that stifle its reach into  hard currency and all ow it to know with total accuracy where every coin sits  and  also control its use and tax it.   Right now there is a lack of trust, legitimacy  and purpose in almost all of the exiting crypto currencies.   They have to converted to real money to become useable.
