Lots of great answers, this is a great place to learn about blockchain. Should have come here long time ago.

Thanks everyone for participating.


Ah yeah, my bad, but you got it exactly right. I want to control my change addresses manually. I see you can unhook "use change address" in Electrum. I wonder how that looks... Your input gets as output as well together with the withdrawal address?

Anyway, if any of you knows the easiest way to put a P2HS as change address from a P2PKH, please let me know. This could be smart to do if you want to transfer your funds to segwit to get lower fees, huh? So you just wait to transfer them till the next time you gonna pay for something else. I know you can do "pay to many" as well in electrum, but that makes the fees higher i guess.

Thank you so much for that screenshot, really helps me. I just noticed I need balance on my Electrum account to get to this step, auch. Maybe I can connect my trezor to it, hm. I came across the testnet as well, is that somehing to recommand? Anyone got easy guides?

One more question (i probably get more later when i try the transaction):
In case of using locktime, does it have to require two actions? One for locking and one for receiving (broadcasting the transaction) or is it possible to like "auto broadcast" at a specific block/time?

Thank you all again for replying, Ive red all of the posts.

 

Hello guys,

Im new here, but not new to Bitcoin. Thank you in advance for your warm welcome, thank you thank you.

Me and my friend have been using blockchain techonology for echonomic speculation for few years now. Now when that has become such a mainstream we are bored of it and wanna try to learn more about how it actually works. We know all the basic stuff as change address, mining, mempool, mixing etc. But we recently started to challenge eachother with tasks. So my task now is following:

Do the following in one same transaction:

1) Use locktime

2) Fee below 300 sats

3) Send from a P2PKH address (legacy, prefix 1) and set P2HS (prefix 3 address) format.


Now, locktime aint hard with the correct software. I know that Trezor can use it easy, but I got no Trezor. Other software or coding lines is  appreciated.

Fee blow 300 sats is abit scary cause its a huge risk for the transaction to stay stuck for some time. I know using RBF will help me out if things are getting nasty, but it wont help me much with the task itself. Impossible you say? Well, I have seen several transactions made it.

I have never set a manual change address. Ive only used the automatically given ones. So here im quite lost.

Why on earth havent you just googled or youtubed it? Well, I have, but try to search on something technical on cryptocurrency on the internet without getting spammed by youtubers trying to get you to buy shitcoins.

And you might call me a cheater. Well, jokes on you. All help is allowed, the main goal is to learn.

So if anyone of you nice bitcoin talkers can help me out or share your experience, I would really much appreciate it.

Peace out, Sim33.
