I know what thread you are talking about and I personally did not say that. I said 1 BTC = 1 BTC. It is already stable. That is the answer! All of the other inferior currencies are the ones that are unstable against Bitcoin.
It is not suitable for you to just generalize that entire thread and skew everyone's posts to suit your opinion. Unacceptable.
Almost all platforms and even some wallets require your ID which is the opposite of anonymity.
If you open your eyes you will find many platforms like HodlHodl and Agoradesk that allow you to trade locally. You can also use kycnot.me to find other privacy/no-kyc enabled services. These are good services, and you pay for them in fees. If you want cheap fees, add your ID to an exchange. Just because fees are higher (because you gain privacy), does not mean that they are bad platforms.
You pay for privacy. If you want to use a platform without ID, expect 1-2%, sometimes 3%. If you build relationships with local traders, maybe less. That's business.
Almost all platforms and even some wallets require your ID which is the opposite of anonymity. And because of that there are fewer and fewer platforms that offer you services without KYC and therefore because there are not many of them here they hike up their fees to the sky.
Add to that the fact that even wallets are not safe. Ledger literally offered people to save their seed phrase in the cloud. The mere fact that they CAN take your seed phrase and upload it somewhere is a reason to never use ledger anymore.
That's why I think that bitcoin Ideas are dying.
Bitcoin has not faulted in its ability to serve as a currency since it was created. If you can transfer Bitcoin globally and cheaper than a bank, it serves as a better alternative currency. If other currency fails and you can still use Bitcoin to pay others, it serves at as a better alternative currency. Just because people speculate Bitcoin, it is not a currency? It's ideas are dying? Please. Stop.
