This only applies to Bitcoin, and as anyone can see even big operations like Coinbase trade in at least three difference crypto currencies.
>> - It's easy to store wealth in without being obvious to others.
Can you elaborate on exactly what benefits you propose this offers? And don't say tax evasion.
>> - It is easier to transport bitcoin than any significant amount of wealth
We've been able to send money all over the world for decades now, I can literally send my friend in New Zealand $50 using an app on my phone. Not sure how Bitcoin makes this any easier. Maybe it makes it a bit cheaper, assuming it's value doesn't plummet while your transfer is going through?
>> - It is easier to protect bitcoin than gold. Gold has to be guarded, Bitcoin can be split in to an n-of-m key and encrypted and replicated, securing it from fire, theft, etc.
This is a hard sell. Your choices for storing Bitcoin are basically keeping it in some sort of online wallet through an exchange or an application running somewhere, or you can store it offline ie a paper wallet. I don't see how this is any easier to secure than putting a pile of gold in a vault.
Bitcoin is probably even less secure for the average person - all it takes to hijack a wallet is a simple key logger. Once your wallet is gone it's not like you can contact your bank to get it back or have transactions reversed like you would with a normal account. Not to mention all the millions of USD worth of Bitcoin that have literally just been lost forever by people forgetting a password, tossing out old PC's etc.
