I warned you it sucks  

https://dogecoin.com/wallets/ has 8 wallets for Android and iOS.

Doge is not being developed. Go private and use XMR instead.

Coinomi can still do this, but the wallet sucks.

AFAIK, multiple wallets still do. Electrum should be one of them. Exodus also allows you to sweep a private key from a paper wallet, and it also supports BIP39 (in case you have it encrypted).

This is not going to "convert" the private key to a seedphrase though. You have to create a standard wallet first, and when you sweep, the funds will be sent from the private keys/paper wallet address to that wallet.

Completely disagree.  Don't get me wrong I am a big privacy advocate. I use signal as often as I can, I'm a big fan of Monero etc.  But if you make bitcoin a truly anonymous coin, it's going to face far harsher scrutiny from governments and a sizable amount of governments will simply ban it for that alone.

Think about it this way, some countries allow for zero freedom of speech, women who cant vote, drive, or show their face in public, etc etc... you think they are going to allow for a monetary system that they absolutely can't track and regulate what so ever? The answer is no.

The thing is most people actually don't care about their privacy. They say they have "nothing to hide". With this mindset, we can never expect governments to give up on their task to destroy privacy for good. Bitcoin by itself may not be private, but there are tools you can use to help make your transactions private. For instance, you can use a non-custodial mixer to obfuscate your utmost sensitive transactions, or simply convert your BTC to a privacy coin like Monero or Zcash.

Some would say using a new BTC address for each transaction is the perfect measure to help protect your privacy. The problem here is that you're stuck with centralized exchanges which force you to provide your personally-identifiable information. Decentralized exchanges exist, but they have low trading volume/liquidity compared to their centralized counterparts. Not to mention, they're not as easy to use as you think they are. With the introduction of CBDCs, governments will become more invasive than ever. It'll be up to crypto advocates to help defend privacy for the sake of our liberty and freedom. Just my thoughts

Adding a privacy feature to bitcoin is a good idea but on the other hand there is already a privacy coin called monero and the exchanges are banning it left and right… What do you think would happen to bitcoin if it was also fully anonymous? It would probably get banned from the exchanges too. Without the support from the exchanges bitcoin adoption would take a huge hit. Most crypto activities are happening on the exchanges and that’s pretty sad imo.

Privacy of some sort on the protocol level will be very difficult and will take a lot of time(assuming it would actually occur someday). Also, I'm pretty sure privacy is frequently being talked about even before this incident you're referring to. Safe to assume that adding privacy(regardless if on other layers or on the main layer) is simply just not that simple to be implemented in a few years.

No. What we should be fighting against is the blacklisting nonsense. There are ways to protect yourself from trivial de-anonymization, even if the majority doesn't utilize them. The problem doesn't lie on privacy techniques, but on users who are confident with accepting arbitrary rules to pass from entities that don't want their good, and that rely on irrational mechanisms such as blacklisting every coin that comes from a mixer.

And we should fight for privacy protection, of course. The Lightning Network is a significant on-going update for those who value privacy.
