I started an online store that accepts cryptocurrency - Bitcoin, Litecoin, Doge and a ton of others.
I just bought Fallout 4 for $25 in bitcoin (usually $60). Easy to pay, got the code within 5 min. Why would retailers not adopt this?!

Scrub looking to start at ~$150
I'm looking to start at ~$150 I know very little. Looking for any helpful buying advice. Is buying used a legit thing? I've seen the Antminer s3+ at $150 which would take 147 day to break even with free power and no power supply. I've looked around the Reddit and found very little that would be helpful recently. Thanks

How can I know more about bitcoin mining and how can I start if I have free electricity?
I have free electricity in my university. Unless I am taking down the whole university network, nobody cares what I use.
So, how can I get started mining for cheap? What do I have to buy?
I am not looking to make a lot of money, but if I earn a little something and learn more about bitcoin on the way, it will be a win in my book.
Please help a noob out!

Bitcoin dev IRC meeting in layman's terms (2015-11-26)
Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms.
Link to last weeks summarization
Note that I crosspost this to Voat, bitcoin.com and the bitcoin-discuss mailing list every week.
Disclaimer
Please bear in mind I'm not a developer and I'd have problems coding "hello world!", so some things might be incorrect or plain wrong.
Like any other write-up it likely contains personal biases, although I try to stay as neutral as I can.
There are no decisions being made in these meetings, so if I say "everyone agrees" this means everyone present in the meeting, that's not consensus, but since a fair amount of devs are present it's a good representation.
The dev IRC and mailinglist are for bitcoin development purposes. If you have not contributed actual code to a bitcoin-implementation, this is probably not the place you want to reach out to. There are many places to discuss things that the developers read, including this sub-reddit.
link to this week logs
Meeting minutes by meetbot
Main topics discussed where:
CLTV activation
BIP68/BIP112 implementation
Replace-by-fee
Short topics/notes
It was an American holiday (thanksgiving), so there weren't a lot of people in the meeting, which started later as well.
Personal note: My weekly posts are being read by more people than I ever anticipated and people are expecting these to come weekly.
Next year starting Mid-February I'll be on vacation for a month, so that's 4 or 5 meetings I won't be able to do.
If there's anyone who's up for the challenge to take over during those weeks (or maybe just 1 week and share the load with others) feel free to pm me.
I'm announcing well in advance, so there's more chance to find someone and to not make this a last minute thing.
I'd prefer someone who doesn't work in the bitcoin space (coding), as I much rather have people work on the future of money instead of enlightening us noobs :)
CLTV activation
- background
CheckLockTimeVerify (CLTV) aka "how you thought nLockTime worked before you actually tried to use it" aka OP_HODL.
- meeting comments
It's plausible the CLTV softfork will activate within just a few weeks, as everyone but a few big miners have adopted it.
About 20% of the nodes currently run CLTV-supporting versions. The negative effect of not upgrading is a degraded validation (SPV).
- meeting conclusion
Do a social media reminder to upgrade nodes to v0.11.2/v0.10.4
BIP68/BIP112 implementation
- background
BIP 68 Consensus-enforced transaction replacement signaled via sequence numbers , and current implementation.
BIP 112 CHECKSEQUENCEVERIFY, and current implementation.
In short: BIP 68 changes the meaning of the sequence number field to a relative locktime. BIP 112 makes that field accessible to the bitcoin scripting system.
- meeting comments
The BIP68 and BIP112 texts have been updated to match the implementations.
There's been a call and discussion to rename CHECKSEQUENCEVERIFY on the mailinglist.
btcdrak wants both pull-requests to be merged soon, others feel more hesitant as people seem to only recently started looking at it seriously.
- meeting conclusion
Merge updated BIP-texts
Replace-by-fee
- background
Currently when a node sees a transaction that spends the same output it ignores it. With replace-by-fee it replaces the current transaction in the mempool if it has a higher fee.
This allows for things like spending "stuck" transactions, adding more recipients to a transaction in order to prevent chaining, etc.
Since there are people that accept 0-confirmation transactions and this would make it extremely easy to double spend them, this is made opt-in.
The sender can choose to opt-in to replace-by-fee by changing the nSequence field of all inputs.
This is a mempool policy for the upcoming 0.12 release. There's a good FAQ-ish post on reddit about it.
- meeting comments
petertodd ran some tests with the mempool limiter turned way down and saw no issues.
It should be technically easy to merge first-seen-safe and full-unconditional as options if there's people who want to write it in.
- meeting conclusion
test and ACK replace-by-fee (Has been merged meanwhile).

Before the end of 2016, a countries central bank will officially add bitcoin to their basket of reserve assets. Inevitability in action.
In the same way, and for the same reasons as it is smart for an individual citizen to hold a small amount of bitcoin. It is more so the case for central banks to hold a small amount as part of their reserve assets.
The same phenonemon that naturally took place over the past 5 years with individuals is about to take place with central banks asset reserves. Once the first central bank makes the move, the game is on, and what central bank on the planet would want to risk getting left behind on the train that could completely destroy their countries balance sheets if it succeeds.
Kudos Barbados! Lead the charge!

Stuck transactions
EDIT: The Bitcoin network is currently under a sophisticated DoS attack using the "fake sigOp" method...
Some weird shit is going on right now: mempool size is above 10 MB total, with a total size of transactions paying at least the default recommended fee rate (10 satoshi/byte) being 8.5 MB. (Numbers from here). So there is definitely enough fee-paying transaction to fill several blocks with.
However, most blocks are far from being full, they do not even reach arbitrary limits set by miners. For example, you can see block #385917, mined by a KnCminer, having size 912 KB, and the next block #385918 is only 487 KB. So we see that KnCminer is OK with mining blocks as big as 912 KB, but found only 487 KB of worthy transactions.
Thus we can conclude that some anti-spam filtration measures are on, but what are they?
I think we might benefit if miners state the policies they are using, as it gives wallet developers a chance to change the way they make transactions, or at least warn users if transaction won't be confirmed soon
I just got a transaction confirmed after 4 hours of waiting. It wasn't a low-fee transaction: it paid about 20 satoshi per byte, which is twice the default fee rate. I think I know why it was delayed: it had an output which is only 3400 satoshi, which is only slightly above dust threshold, perhaps it made transaction look spam-like.
It's frustrating that miners' policy is so opaque. Let's look at block #385927, which is mined by F2Pool. It is 340 KB in size, which is smaller than other blocks recently mined by F2Pool, so we know it didn't reach the block size F2Pool set. No block explorers I'm aware of show transaction fee distribution for a specific block, so we have to do this manually. However, we can take advantage of the fact that Bitcoin Core sorts transactions by fee rate, thus if F2Pool uses block constructor based on it we will see this pattern.
5 of the last 7 transactions in the block pay almost exactly 20 satoshi per byte, so this seems to be a cut-off rate. The last two pay less than that rate, however, they coalesce many outputs, so it might be a result of prioritization.
The question I have is why do we have to learn about it through guesswork, aren't miners themselves interested in Bitcoin being a reliable payment system?
It's hard to figure out what the fuck they want from us even using fairly sophisticated statistical tools.

Who uses 0-conf transactions?
Honest question, there it a lot of talk about how opt-in replace by fee breaks 0-conf transactions.
I have always thought that no one usages 0-conf transactions anyway because they are not safe but there seems to be a lot of outrage about it. All the exchanges/services I use use between 3-6 confirmations so yeah.
Who uses 0-conf transactions? If I could get a few links I would understand the outrage better.
