If it sounds too good to be true, i.e. 3% interest per day, it is ALWAYS a scam.

Many investors would give their left nut to get a reliable 3% PER YEAR let alone 3% daily.

Terrible idea - the coins would immediately be converted to fiat and the price would crash.

Would be MUCH better to just destroy the coins by sending them to an address with no known private key. That would benefit the whole community not some random group of "lotto winners". Think about it - why should some random group who have made ZERO investment in BTC benefit from the technology?

Full blocks are no big deal - just increase the fee to a reasonable level and your transaction should go through no problem.

The problem with Bitcoin is that the network has become VERY expensive to maintain and is borderline unprofitable for most miners. As a result, nearly all the mining has been concentrated in China where space and power are cheap.

It is very unrealistic to assume that the price of Bitcoin will just increase arbitrarily to ensure miners stay profitable. That assumes a continuous increase in the number of investors who horde the coin. With prices down from a peak of $1000+ to under $400, many prospective investors got cold feet and it can easily be argued that the long term trend is now down not up. If BTC is used primarily for transactions the price could fall back to $100, or $40, or $5. There is really no floor.

Not until:

1. Deposits are guaranteed
2. Transactions are reversible
3. High transaction volume and user adoption
4. Near instant verification
5. Technology is distributed not controlled by a few miners in China

May happen eventually but not sure if BTC can get us there

If the book is really good and original you might be able to get the loan. Recommend you share some of the content here so potential lenders/investors can review the quality of your intellectual property.

The China crash, and crash in US markets, likely has more to do with Bitcoin price depreciation than any fundamental issues with the currency. I'm still on board.

Put $52k in a mix of 50% bonds and 50% stocks. You should be able to draw $2080 per year, which is the same as $1 x 2080 hours, in perpetuity.

Ugh block finally solved after an hour and my transaction wasn't in it. Paid .0001 fee. Someone must be stress testing.

Current block now over an hour... This is pretty darned painful since I'm waiting on a .5 BTC purchase to clear.

If an event happens so catastrophic as to wipe out all global copies of the blockchain, I assure you a BTC balance will be the LEAST of your worries. Play some Fallout for reference.

Serious question - is OP an idiot? Fed has been telegraphing for MONTHS that the rate increase will be .25% and any further increases will be measured and far apart.  Zero probability of .5% and negative probability LITERALLY LESS THAN ZERO that it would be 1%.

If OP is willing to escrow, I'd be happy to bet as many bitcoins as he has that December rate increase will NOT be 1%. OP game?

Of course not - they will have spent all of it on Apple products

The major problem is it is utterly useless for 99.99999% of retail transactions. "Accepted Nowhere" wouldn't be 100% true but for all intents and purposes it is an accurate statement.

Begs the question - what is it useful for and why are people paying $330 per BTC? Seems like a bit of a Tulip-mania where most users are just chasing returns rather than use the coins for conducting commerce.

Earning 1 bitcoin from faucets would take forever at current drip rates. OP is dreaming if he thinks he can get 1000.

As for gambling, sure OP can buy a lotto ticket but 99.9999999% lose the lotto. All but guaranteed he'll be one of them.

Looks like it was a 3kb transaction but they only included a fee of .1 mBTC. .1 mBTC is usually added per thousand bytes so the fee should have been closer to .4 mBTC. For that reason, miners are not including it in blocks.

Best bet is probably to contact the cloud mining company and have them resend the transaction with a higher fee.

Solve by inspection that Martingale does not work.

A few argue that it works with infinite bankroll but betting has no meaning if you have infinite money since your ROI will always be vanishingly close to 0%. ($finite/$infinity = 0% bankroll expansion per wager won)

D-Wave is very controversial. Quite a bit of evidence that it is no faster than regular computers and that any efficiency it appears to have in tests appears to be from clever programming not quantum computing.

Goes without saying that Bitcoin kicks D-Wave's ass. If you put every machine D-Wave has ever built to work mining, I doubt the capacity would exceed one $9.95 block erupter. They are that bad.

Dilution - miners presently receive a reward when they mine a block. Hence, the real cost per transaction is (value of 1 BTC * size of miner reward) + fees / number of transactions. As it turns out, there are relatively few transactions per block and the mining reward is fairly hefty in USD equivalent. Hence, the high cost per transaction. This should go down over time as the currency increases in popularity and the block size cap is lifted.

Note that the Bitcoin network presently pays about $5.8 USD per transaction. That includes some fees but mostly the mining reward.

A bit irresponsible for people to abuse low transaction fees to spam the network particularly while the 1MB cap is in place.

That would have been nice but no I was betting 5 units of .001 BTC and hit the Progessive Royal for a payout of about 4.2 BTC. Still happy with it!
