Some emerging opportuniuties and advantages for cryptocurrencies

Some adantages of cryptocurrency

1. Low transaction fees
2. The potential for Sharding and off-chain transactions to contain mining costs
3. The benefits of a platform like Ethereum to include and implement business processes
4. An immutable and traceable ledger that bypasses manipulation by governments that simply print more fiat currency
5. The intrinsic ability/ advantage to handle micropayments and transactions, especially in the third world.
6. The real need for an alternative to banks in the third world
7. Any fiat currency and gold and cryptocurrency is dependent on the acceptance and confidence of its users in it as a store of value, so why is fiat any better - especially when governments fail?

I don't pretend to be an economist, but I sure trust geeks like Buterin more than politicians like Trump or McConnell. The real important question is who should set value - the crowd or the old guard.
