Fun of gambling because we can play. Gambling is fun because gambling game that is very interesting in my opinion. Such as dice, poker, sports betting. Bitcoin I played when I was in need of comfort. Perhaps fun is in gambling because gambling is a game.

Gambling can be profitable in REAL casinos using professional methods of card counting and bankroll management combined. Just search the MIT Blackjack Team as one example. Online Casinos you will not be profitable in the long run unless you hit a jackpot, or are a sports bettor that has the skills of a professional handicapper.

If you have a serious problem on gambling addiction i think you need a special handling from a professional . You will always under supervision , controlled and have a good advice that will make you feel better.
If you want a temporarily dissapear and stay away from gambling habits and have a plan to get back later, you can block all the gambling sites as you want.

Ah! Fixed my slowness a bit I opened the debug window and used "reconsiderblock" followed by the hash number for the block. it had been stuck at. The CPU utilization went way up, then bitcoin-qt crashed. Restarted at a slower overclock and it seems to be chugging along.

Thanks for this. I've been trying to get a node up and running myself here. Very slow to sync, maybe a few weeks of blockchain history per day. I'm on a decent connection, ports are properly opened and I see lots of peers. CPU usually runs at under 10%. Set the cache to 500 MB, tried to increase the swap file to 2 GB, stably overclocked to 1100 mhz but not much luck with faster syncs. I'm trying to figure out my real bottle neck.

I'm using a 32 GB SanDisk Ultra: http://www.amazon.com/gp/product/B010Q57T02?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

As well as a 128 GB Cruzer Ultra Fit: http://www.amazon.com/SanDisk-Ultra-128GB-Flash-SDCZ43-128G-G46/dp/B00YFI1EBC/ref=sr_1_5?s=pc&ie=UTF8&qid=1445887029&sr=1-5&keywords=cruzer+ultra+fit

And a Wifi N dongle.

Now I realize the Cruzer Ultra fit doesn't have great sustained write performance. I guess I thought my connection + the USB 2.0 interface on the RPi was such a bottleneck it wouldn't make sense investing in a really fast USB 3.0 drive, and I liked the compact size.

What's my biggest bottleneck here, probably? Would hooking this up to Ethernet improve performance since all the USB ports are limited to one bandwidth? If it's the USB drive, what do you think about a cheap SSD like this: http://www.amazon.com/dp/B00EZ2FRU2/ref=twister_B00PB9BSIS?_encoding=UTF8&psc=1

At some point this does get economically inefficient. For the price of the USB drive alone I could buy an old windows Atom netbook with a bigger drive and 2 GB of RAM- an all in one node solution. Now I'll admit this is a hobby project for me, but it does seem a bit wasteful to go about buying this high bandwidth stuff the RPi2 can't really take fully advantage over.

I'm in the same situation. Blockchain had been synchronized, but it kept falling behind. 56 connections, ports were open. Connection is solid, fiber optic 25/5. I tried reindexing to no avail. I just uninstalled AVG and, coincidence or not it suddenly resynced. So do you have any antivirus programs running?

Running Multibit is a fine fix, but I feel like if I'm already going to have a computer on 24/7 with plenty of space I might as well run another node with the full block chain to keep the network strong.

No I don't think so. That's why I have paper wallets and CDs too. Not sure about MicroSDs resistance under those conditions. Also my backups are geographically spread out, so I'd be able to recover the wallet even if all media were susceptible.

Rate this security setup for a wallet I rarely plan to withdraw from:

Encrypted multibit wallets with ample unused additional addresses running on my laptop. (very strong password ~15 characters, mix of upper/lower characters, numbers, no words)
Backed up to Dropbox to protect against a local failure.
Saved to several USB drives, micro SD cards, paper wallets, CDs, all encrypted as AES256 compressed files in addition to wallet encryption so people don't know media even contains bitcoins.
Several micro SD cards, CDs and paper wallets sent to friends and family members across the US for safe-keeping. They don't know the passwords.

Protection against:
[X] local hard drive failure, accidental deletion
[X] dropbox failure
[X] EMP attack
[X] destruction/search & seizure of my residence
[X] localized mayhem
[X] jealous friends spending Bitcoin
[X] laptop thief, jealous friends, Feds transferring bitcoins, dropbox hacker getting wallet access
[X] basically all dictionary attacks and even a botnet brute forcing my password
[  ] rusty pipe attack (being beaten with a pipe until I disclose the password/location of wallet)
[  ] memory loss
[  ] destruction of dropbox, my computer and each and every backup

Is this decent security for a wallet I'll be holding ~$20-100k+ in?

Bump

Not necessarily. You have to assume people will not purchase a mining unit when there's a negative expected ROI which isn't true for economic and non-economic reasons. People may expect bitcoins to appreciate and anticipate a positive ROI. Or they may value being able to participate in securing the network, the novelty or the conversational value that a flashing USB stick can have. If USB ASICs drop to $5, these non-economic factors become even larger. People will pay $10 for a humping dog USB gadget which generates 0 bitcoins, totally plausible a USB ASIC could command a premium too.

Also, your analysis only applies to the current generation of USB ASICs. Chip advancements typically allow for faster and faster chips with almost no increase in fixed unit costs. If ASICs get substantially faster (which we would expect under Moore's law) the ROI will look less shabby.

The value of bitcoin is going to depend on demand and usage. If the size and usage of bitcoins approached the value of major currencies, the value of a single bitcoin would have to be astronomical given the constrained supply.

There's currently $1.2 trillion USD in circulation as cash money, $2.5 trillion when you count checking accounts, $10.5 trillion when you add in money market funds, savings accounts and CDs. If the usage of Bitcoins approached the size and value of the dollar economy, for the 20 million bitcoins to replace the dollar in current usage, the value of a single bitcoin would have to be over $500,000, and over $1,000,000 USD if it became the single global currency. Obviously that's rather ambitious. But if bitcoins are ever to become semi-mainstream, the sheer demands of even a million new users trying to conduct transactions in bitcoins would easily drive the price to $10,000+.

It's pretty simple. You have a company, like the credit card company, which screens potential customers in advance and decides to accept a certain risk of double-spending or insufficient funds up to a limit. In exchange, the company receives a small fee from the merchant and reserves the right to bill the customer if there's insufficient funds. Merchants get instant confirmation when user swipes card or provides authentication they have an account. Just like a credit card company, the merchant gets paid whether or not the customer can foot the bill, whether it's 30 days later for a credit card or 10 minutes-a few hours for a bitcoin transaction.

Correct. It was not the most optimal decision for the best ROI. I'm chalking up the difference in returns to the value of the fun of having the unit, tinkering with it and it being a conversational piece. There's definitely a luxury non-investment component to my decision.

It's sort of like people who raise their own coop of chickens for eggs. They'll never be able to produce eggs as cheaply as efficient factory-farms or even big cage-free organic farms, but they do it anyway because it's kind of fun to make your own.

  Oh you're a real kneeslapper!

It's hard to do because of the uncertainty in getting a reliable USD/GH figure at any particular timepoint, what with long backorders and limited availability. Still I think most mass-produced units will not produce their value in bitcoins at time of purchase in their lifespan.

People may get a positive return on a fair number of units in USD, but investing in bitcoins instead of buying the miner almost certainly will generate greater returns.

Looking to sell my 60 GH/s single currently in hand in Virginia. Includes overnight shipping. Asking 50 BTC.

I've posted pictures in another thread when I was optimizing the performance. Case is currently off and can be shipped either on or off.

[[EDIT: SOLD]]

I paid cash for a BFL 60 gh/s unit at a pretty heavy markup in USD. While I don't think the unit will ever generate the number of bitcoins I could have bought by investing that money directly in bitcoins instead of the unit, I do expect the USD value of my BTC will eventually exceed what I paid.

Also I applied 3 days ago for BitPay and have yet to have my account activated.

Why should I choose BitPay over Paysius?
