It might have been but it is very much not. It's non fungible and transparent resulting in coins, wallets and transactions getting easily traced and blacklisted meaning they can be put into a limbo where nobody is willing to accept them anymore burning there value.
The actual solution would be a fungible and private coin like monero where any of that is impossible by design.
Yes, I agree that Monero is likely a better option. I am also a big fan of Nano because of its instant transactions and zero transaction fees. However it has the same privacy problem as Bitcoin. It would be interesting to see a hybrid of Nano and Monero.
