Immediately losing peers when using bchwallet in SPV mode

I'm trying to use bchwallet (https://github.com/gcash/bchwallet) in SPV mode, as described in this article: https://medium.com/@bchd.cash/announcing-neutrino-wallet-for-bitcoin-cash-eb7a85a49c0e

I can see that the wallet is finding a bunch of peers and trying to download block headers from those peers. However, it appears that each peer gets immediately dropped once the wallet starts trying to download block headers. Once all the discovered peers are dropped, the wallet simply stalls.

I tried manually adding a specific peer by using the --addpeer option to add bchd.fountainhead.cash. When I did this, rather than stalling, I could see that the wallet kept trying to reconnect to that one peer, but the peer was immediately lost each time.

Has anyone gotten bchwallet to work in SPV mode? Any chance of some pointers on what I'm doing wrong?

Command I run:

./bchwallet -u blahblahuser -P blahblahpassword --usespv --rpclisten=0.0.0.0:8332 --noinitialload --addpeer=bchd.fountainhead.cash

Sample output:

2021-04-01 09:08:37.174 [WRN] BCHW: open /home/nick/.bchwallet/bchwallet.conf: no such file or directory

TIL never ever tell someone about your bitcoin

I met a random guy recently and we talked a little bit about random stuff. After a while he came up with Bitcoin and asked me about my opinion. I told him that I own Bitcoin but not the exact amount. Anyway, it turned out that he had a certain level of criminal energy and had a ton of crimes convicted over the last years. Conversation went like: "I'd never harm somebody, you know that. But if I could make some fast money I'd get my guys, kidnap you and cut off your fingers until you tell me your seed". We had some beers and continued with some different shit. But right now I am searching for some self defense tools. I've never felt so uncomfortable. Hope things will not get ugly. Here is my advice: No matter how much you love the technology or how badly you want to share your Bitcoin story: Don't tell someone unless you are not 100% sure that he is trustworthy. Don't be foolish like me.

Bitcoin is DeFi, and It's the Biggest Cultural Fight of Our Lives, the Separation of State and Money

When discussing the regulations about defi you may believe it only applies to altcoins. This is deeply wrong and misguided. First of all there are platforms being developed that use unwrapped native bitcoin. Second of all, any of these laws against DeFi in general will absolutely destroy the future of bitcoin as an independent government free tool. It will be fully controlled by KYC, globally, in every single area except private wallet to wallet transactions. anything that so much as looks like Local Bitcoins will be KYC'd with extreme prejudice. You will have no real fundamental freedom from the government. Microsoft is even developing bitcoin layer 2 smart contracts that have built in KYC.

Chainalysis will be used against you with extreme prejudice, very little bitcoin will truly be fungible, and it will be dangerous to acquire.

What the bitcoin community tries to convey as a antithesis to altcoins, to me really comes across as an antithesis to layer 2 solutions.

Bitcoiners do not want to deal with the regulations that will fundamentally dictate layer 2 and lightning network, yet if the western governments get their way, none of these layer 2 functionalities will ever exist without KYC and mass surveillance, ergo you will never see the separation of money and state.

This is why the definition of non entities, non companies, non custodians as vasp is a mortal threat to liberty and the values of bitcoin. It's why the travel rule is so bad. It prevents any real freedom from this state intrusion.

You as a community need to realize what layer 2 is, what web 3.0 is, and defend it, because it is the most important cultural battle of our lives.
