I think you do need to elaborate. Bitcoin may need specific actions depending on what one desires and what one’s threat model is. But completely dismissing the privacy part is not helpful. I’ve used Bitcoin and other cryptocurrencies for some payments that I wanted to be private. I couldn’t ever have done that with conventional payment systems without more exposure than with the cryptocurrency.
As someone who’s been into some cryptocurrencies and later realized what bitcoiners have been saying all along — I’m a bigger believer in Bitcoin than I was when I started. Not too much on Bitcoin as a currency, but in its potential to hold value over the long term. I haven’t had the chance to try Lightning for payments yet. The other one that I prefer to use for payments is Monero.
