2014 bump

Doh, ... too late.  Agorafest 2014 was last month.

And there was an event earlier this month and several events last month (including a booth a the State Fair !!!):

So join that meetup group if you haven't yet and it'll send you e-mail when any upcoming meetups get scheduled.

I don't think transactions can get lost? that would be ridiculous  Huh

Happens all the time.

Transactions that don't confirm (e.g., with six confirmations) eventually get dropped by the miners (due to the limited size of the transaction pool which is in-memory only.)

There is even the possibility for a confirmed transaction to get "lost".  That happened with the March 2013 hard fork where a customer deposit to OKPay had confirmed, but then that customer took advantage of the hard fork situation to create a double spend against OKPay.  Due to the situation, the miner that included the double spend (BTC Guild) had already known of the original transaction on the v0.8 side of the blockchain fork but then included the double spend of that same transaction when they switched to solving blocks on the pre-v0.8 side of the fork.      So BTC Guild "lost" the first spend transaction -- likely due to re-starting the client which, at the time, had no method of pulling the transaction memory pool from a peer or from permanent storage.   

That's a very, very rare situation.  Though it could have been a $10,000 loss to OKPay had the customer not returned the funds that were double-spent.

Halving was already priced in to the exchange rate by speculators -- so it occurring didn't cause a shock.

Halving was not really considered by most miners.  Many of them were pretty surprised to see their yield drop (in terms of XBTs) by half.  Some of these miners had bought mining hardware because buying at an exchange was difficult, at best.  So when the returns (in terms of XBTs) dropped there was some buying pressure once they discovered that methods available from the exchanges had improved.

Now that a much greater part of the world has exchanges, that buying pressure from the miners that came with the first halving won't repeat for the second halving.

Since many miners sell much of their bitcoin revenues, this next halving will likely have a bigger impact on liquidity after the halving occurs than the first one did, IMO.   i.e., the loss of supply of $50K /day (calculated as 3,600 XBT/day at $14 each) had a lot less impact than will $1 million/day (calculated as 1,800/day at $555 each, or whatever it will be then).

What about you? Do you value your credit scores?

Sorry for the necro thread post but I thought this was relevant.

Americans In Debt: 35 Percent Have Unpaid Bills Reported To Collection Agencies

Poverty Is Profitable: 1 out of 3 US Consumers in Debt Collection

Oftentimes the debtor gets reported, but then the next time they go to the bank to get a car loan or something like they they are told they need to pay off the debt owed before the bank could even consider lending to them.   So this "leverage" that the lenders have seems to do a decent job of recovering a fair amount of previously bad-debt.  When even that doesn't get the debtor to pay up, once in collections there are often threats of it going to court to get a judgement (which can result in "enforced judgement" that includes garnished wages, attachment of assets, liens on property and bank levys).

Does Bitcoin provide a relief from this for many?   A freelancer receiving Bitcoin income probably isn't worried about garnishment of wages or a bank levy even.

Also, a borrower with bad credit in the fiat world might still find lenders on BTCjam or BitLendingClub.  It's like a second identity since the fiat world uses one trust system and the peer-to-peer economy uses another.

I don' know enough about Mastercoin to how how this will work.  Does the "issuer" (e.g., Realcoin, Inc/Ltd/???) have the ability to censor transactions, and/or reverse transactions?

I read the mastercoin whitepaper a while back.  I don't think so.

It will be interesting to see if they are successful at getting licensed as a money transmitter in the states where that's required.

I can't wait to see what happens when you pair a digital currency with the looming failure that is the US Dollar.

I don't know enough about Mastercoin to know how this will work.  Does the "issuer" (e.g., Realcoin, Inc/Ltd/???) have the ability to censor transactions, and/or reverse transactions?

Is this really press of an alt ANN?

Yes.  About the only reason this would be even remotely related to Bitcoin to justify its inclusion here is that Brock Pierce is a Bitcoin Foundation board member.

Further discussion for this announcement probably should go here:

Grin crypto-currency backed by FIAT ...

I'ld think of it as being something of a current account -- the same thing that customer deposits are referred to by banks, PayPal, Dwolla, etc. etc.

If this were a decentralized cryptocurrency (e.g., using proof-of-work), I don't know how they'll be able to get a money transmitter's license as they are said to be planning.  But this is on Mastercoin.

I don' know enough about Mastercoin to how how this will work.  Does the "issuer" (e.g., Realcoin, Inc/Ltd/???) have the ability to censor transactions, and/or reverse transactions?

58  Bitcoin / Bitcoin Discussion / Re: Does anyone keep money in their checking accounts anymore? on: July 01, 2014, 12:46:29 AM
Bitcoin is allowing "just-in-time" cash management of a bank account.

This lets the person who gets bitcoin income to use a bank account only when needed (e.g., mortgage or rent payment, etc.)    A transfer from Coinbase takes two to three business days, so if you pay monthly, for instance, you can wait right up until the end of the month to sell your coins and have the cash arrive at about the same time the payment is due.

One might think this is risky because there could be issues -- such as Coinbase canceling the order as "high risk" (which has happened to many, reportedly) but then there is also the same-day backup plan, using (or similar) to get a trade where cash is deposited into your bank account.

So while a person still might keep a bank account, Bitcoin enables one to manage a lower bank account balance.

Physical security when trading in-person needs to remain the first priority.

I just read an interesting statistic:

44% of M-Pesa agents report personally knowing someone who has experienced robbery or theft and the qualitative research revealed that some agents are hiring security guards which is increasing costs.

 - (using browser-friendly PDF viewer)

There is a significant difference between a Bitcoin trader and an M-Pesa agent as far as physical safety is concerned.  The M-Pesa agent needs a significant inventory of cash because there's no way to know how much cash will be needed to support the day's needs.   A person trading Bitcoin knows in advance of doing each trade the amount.   Therefore, the trader being asked to do a larger trade can adjust to give a heightened level of security for trades when prudent (e.g., for larger trades, or with those counterparties who
show few or no prior trades.)

There's certainly good reason banks, check cashers, and even convenience store clerks protect themselves behind bullet-resistant glass, steel cages, etc.  Those trading Bitcoin should be acutely aware of the risks businesses that deal with cash are subjected to.
