    Current governments were never designed for a world of connectivity that both the internet and bitcoin enables. Bitcoin is the largest peaceful protest in history.

    I want to get into bitcoin after watching for awhile

    Posted: 25 Nov 2019 10:56 PM PST

    I have looked at bitcoin but never really thought about buying into it, I have used it a lot to buy stuff and to take payments but I never used it to invest.

    ​

    I have about $2000 in savings, Once it dips more if it does im looking invest at least $1k. my money is just sitting in my savings doing nothing. maybe invest 1k now and then over the next few months put some money in every month so its not all in at the same price. Is this a good move?

    I heard china is getting bitcoin in 2020. will that make the price go up a ton if they all buy it? My buddy was talking about it.

    Bitcoin Core Software Update Now Uses Segwit Addresses By Default

    Posted: 25 Nov 2019 07:10 AM PST

    WB21 I have been waiting almost 2 years for a $5000 transfer from them.

    Posted: 26 Nov 2019 01:38 AM PST

    Been almost 2 years to have funds I "Withdrawn" From WB21 to my UK account its almost laughable. They did not hesitate in receiving my bitcoin. I had given up and accepted I had lost the money as I see no way of recovering it. So I tried one more time recently after months of no contact.Now they don't reply to my emails and my online account seems blocked.

    My bank denied a Bitcoin purchase

    Posted: 25 Nov 2019 10:12 AM PST

    I am not surprised. I am just chocked. My bank denied me the ability to transfer funds from my bank to another bank in order to then use those funds to buy bitcoin on this cryptocurrency marketplace.

    I will change bank.

    1 million per Bitcoin??? Reasonable??

    Posted: 25 Nov 2019 04:16 PM PST

    Many Bitcoin bulls forecast a 1 million dollar Bitcoin. And although I would be very happy to see this happen, that would mean the number of billionaires would double. There are over 2000 wallets with 1000 BTC or more. Is it realistic to think we could double the number of billionaires? The world currently has just over 2000 billionaires.

    Exclusive: ‘Nothing Is Above Bitcoin, No CBDC, No Stablecoins,' Says Blockstream CEO Adam Back

    Posted: 25 Nov 2019 05:50 PM PST

    Would someone please accelerate my transaction?

    Posted: 26 Nov 2019 01:02 AM PST

    I sent BTC from blockchain.info wallet and now the transaction is stuck almost 24h. I need it to be confirmed as soon as possible as I sent it to a service like shapeshift and I think my transaction there will soon be timed-out. Blockchain.info set the recommended fee and I have not changed it.

    my TX is: 84d761a1ad086b70d33c44625bcae6d8ab353912ae3337d10a9edba15e17fa23

    The address it is going to is 3QJ4Ls1Qvc1iY3Zvid5f7zur2cgBX3btBg.

    Thanks!

    Node best practices

    Posted: 25 Nov 2019 12:32 PM PST

    TLDR: How do I manage my small node for personal use?

    Recently I set up a BTC/LN node using Raspiblitz. It was a lot of fun getting it to the point it is currently at but I have a few questions that I couldn't find out by doing my own research. Mostly my questions at this point are on your personal opinions rather than how to's.

    My privacy is important to me but I'm unsure just how private I need to be. Sometimes I think I'm just paranoid or being overly cautious when I need'nt be. I set up my node to connect via Tor because I worry about things like my ISP knowing what I'm using my bandwidth for and potentially throttling or disconnecting my service. I live in the US so this concern might be unwarranted. I also worry about people seeing my IP on places like 1ML and finding out who I am IRL. I have to remind myself that I probably don't have enough money for someone to go through the effort of using this information against me. So I'm stuck wondering if its worth routing over Tor at all.

    I only need two wallets. A spending wallet and a savings wallet. The savings wallet should be on hardware when I eventually get one. My question is do I have a reason to connect my hardware wallet to my node at all? I'm only planning on sending TO my hardware, never from it (at least for many years). I didn't see a lot of guides on how to connect a hardware wallet to raspiblitz so it honestly seemed like it was not common to do it.

    The spending wallet should be on my phone so I can make purchases regardless if I'm away from home or not. I saw a few guides on how to connect Zeus and Zap to the node even over Tor with various tactics like DynamicDNS and Orbot. Someone mentioned that DynamicDNS defeats the purpose of routing through Tor anyways so maybe it's not worth the hassle? Is it possible right now to have the best of both worlds or at least a reasonable balance between privacy and convenience? I also like the idea of being able to manage my channels when I'm away from home as well but this is less important.

    My next concern has to do with routing. I understand the fees I could potentially gain by routing transactions are almost zero. That's fine, I'm not doing it for that, it would just be kind of cool to see something show up on my forwarding history and know that my node helped someone make a payment. Obviously I could never have as much capacity as ACINQ or one of the many online casinos but my (probably misguided) understanding is that I could still be helpful if I balance my channels properly, if not now then possibly later on when lightning gets more usage. Does anyone have any thoughts or resources on managing smaller capacity channels? My plan for balancing is to just buy something using a channel with bitrefill or foldapp so that I have in-bound capacity and using autopilot for outbound channels. Is that a good plan? Questions I've been wondering are things like "who should I connect to as a peer?", "how do I choose who I open channels with?", "is it better to connect to the big nodes or with smaller nodes like myself?", "are there any privacy concerns I haven't considered when opening channels or connecting to peers?"

    Sorry for the wall of text. I just generally like to have things organized and a lot of that is learning all of the options and how to weigh them. Thanks in advance.
