Hypothetical Question:
Not taking into consideration current adoption or first mover advantage but comparing two crypto currencies hypothetically conceived at the same time with the same particulars (emission, etc.) one with a public ledger such as bitcoin and one with a private untraceable one which one would be valued higher and why?
In my view, the private ledger one would become the dominant crypto, it most resembles "e-cash", and takes into account fungibility. I suspect in the future, Bitcoins that have been involved with scams wont be taken by vendors, since it's possible for authorities to track the bitcoins via the blockchain, and most scammers mix their bitcoins(So it'd look like the vendors who accept the tainted coins are apart of the scam).
Basically, if a private ledger currency and a public ledger one started at the same time, I believe the private ledger one would win out. However, the private ledger currency would also have to allow transparency as well. 2 in 1, instead of just 1 like the public ledger currency.
