This is why I have never liked SPV wallets, you are the mercy of someone else when these things happen.
You are at the same mercy with a full node wallet.
The wallet (full node or otherwise) will follow the chain that the developer programmed it to follow. In either case, you are still in control, as you can choose NOT to use the software that you disagree with.
That's right, but I see SPV wallet devs like Electrum more easily to corrupt than Core developers when it comes to following a forked chain, there's also less people developing in Electrum. So an attacker could bribe Electrum devs into having supported the segwit2x chain in the past for example, while I don't see this happening with Core.
And also generally SPV wallets suck in my book, I agree with what Luke Jr has to say about SPV wallets mostly.
The point is; don't use spv wallet (electrum) as the developers easily to corrupt and bribed? We have serious allegations here.
When bch hard fork occurred, people who have bitcoin in electrum wallet could easily get bch by installing electron, even though it's dangerous as the developers remain anonymous and uses the name "Jonald Fyookball". However, people who keep their bitcoin in exchanges which supports bch, credited bch as well without have to do anything.
So, how about b2x? Which wallet is the best to claim free b2x? I'm not so sure right now.
