Comparing bitcoin to bank deposits is not fair: you can't compare a risk-free bank deposit to a volatile bitcoin market. Putting your money in a bank means it more or less keeps it's value, but not much more than that.
If you want to compare profitability, compare bitcoin to the stock market. Many stocks will turn out to be more profitable than bitcoin, you just can't know for sure which ones.
I don't want to gamble on bitcoin only.

Don't worry if that happens, I have a backup of the whole blockchain
And so do thousands of people. That means it can only disappear if nobody uses it anymore, and if nobody uses it anymore, it doesn't matter anyway. Like Friendster, Myspace, Second Life or Netscape. Who cares that they're gone?


There is another interesting possibility though: what if the mining hash rate would suddenly drop a lot? Say because another cryptocurrency comes up and miners move there. Eventually the difficulty should go down, but for that to happen miners first need to find blocks. Assume for some reason 95% of the miners moves somewhere else, blocks would suddenly take 3 hours to be found! Bitcoin would effectively be for a while, but it will come back.

And even if nobody has a backup of blockchain, well, I'm sure hundreds of people would all of a sudden start mining like Satoshi himself did. Starting new blockchains, having a huge collection of bitcoins, and hoping people pick up on your chain again.

What makes you think that? Google "cost of printing money":
$1 and $2: 5.5 cents per note
$5: 10.9 cents per note
$10: 9.9 cents per note
$20 and $50: 10.6 cents per note

If I could print 471 $50 notes by paying 1 $50 note that seems like a very cheap way of creating more money!

The FED doesn't need to print money to do this. They just adjust the interest a bit and punch some numbers into a computer.

Continuing after a win is what gets you eventually. If you start with 1 bitcoin it is quite likely to get 1.1 bitcoin using martingale with small bets. But it is (a bit) more likely getting that by going all-in at 90% chance once. Martingale indeed gives the idea of being safe, while there is no safe way to gamble.

A more fun is "green martingale": start with a small bet, and double on win. Now instead of losing 10 times in a row, you try to win 10 times in a row.

Received Thanks! Two hours earlier than the previous payment, so I don't see any delay

What makes you think there is a maximum to the reds you can get? The next roll doesn't depend on the previous roll. So if you have had 16 reds, chances of the next one being red are exactly the same as after having 16 greens.

The more bets you place, the longer your win/loss-streaks will be.
Assuming 50% chance and 2 bets, chances are one is red, one is green.
With 2^10 bets (1000 bets) chances are pretty big you hit 10 red or 10 green in a row.
Place 1 million (2^20) bets, and 20 in a row becomes very likely.

Usually it's the losers using their loss to "prove" a site is rigged. This is a nice plot twist, your arguments are overwhelming
"I win, so it's rigged"

Every strategy is profitable - until you lose it all.
With a small starting bet and a large wallet Martingale can last for weeks, months or years. At some point you'll risk fortunes for very small wins, and in the end you'll lose based on the house edge.
No matter what strategy: the chance to double your initial balance is smaller than the chance to lose it all.
But it can be fun while it lasts I've seen people use it for months in a row, slowly going up in profit all the time.

Do you have other investments too, to spread your risk (and chances)? 25% of your paycheck on one thing can be very rewarding but can also be very risky.
I don't want to disclose my savings in public, but I can tell you I would never go 25% all-in in any one investment.

I do the same, my signature payments (one payment so far, second one coming very soon) go straight into a paper wallet dedicated to that campaign. I don't need the money now, and who knows what it may be worth in the far future.

I get the feeling the stock market is highly overpriced now. I do have some money in there in some funds, but not much.

Weird logic
Ethereum has always been a pump and dump coin. If you expect it will go up again, there is no reason to wait for it to rise first, you're better off buying lower.
I'm more surprised by the current rise in bitcoin, without ethereum dropping further. If ethereum were to drop further bitcoin will go up much more again.

I hate what Ubuntu did to the default desktop, since they were planning to make a phone-version of Ubuntu. Microsoft tried the same: make an OS designed for phones and put it on a desktop.
Personally I like to keep those things strictly separated: a simple menu-button with a simple taskbar on my desktop, and some random loose icons on my phone. My Linux Mate is already "too fancy" with shadows behind windows and transparancy. You wouldn't print a book on transparant paper, why would you want transparant windows on your computer?

I was expecting (hoping ) for the price to keep going down. It went 10-15% up again since 2 days. I give up speculating for now, I'm still out, I was hoping to get back in, but I don't dare at the current price.

For me it doesn't really matter, long term I assume bitcoin will go up, and short term I am not planning on buying/selling much. The only thing I would benefit from, is going up and down more, as it gives trading opportunities.

I don't see how the increase in price had anything to do with the halving. In this graph I read a very stable price before and after halving, followed by an exponential bubble, a collapse, and a new normal.
Since then the price went up, and down, and the past year went up again to end on the current 400+ (although it has been higher in the past year). Everybody expecting a large effect of the halving must have influenced the higher price, so I see no reason for an increase after the halving. If it happens months later, it is the "normal" variation again.

I think he's right! But not (only) for the reasons in the article. My main reason: look at how many bitcoins are either lost forever or stolen, I've read estimates of 20-30% of all bitcoins ever mined. In just 7 years losing 20-30% is an amazing amount of money, and that is only from people who are bitcoin enthousiasts. Now imagine a 95-year-old has to use a bitcoin wallet, encryption and create backups of it. Of course that has a huge chance to go wrong.

The average person does not understand the current concept of fiat money either. I think barely anybody really understands its debt-based creation. As the article explains: " In fact, 97% of all money is created by banks via fractional reserve banking.", AKA only 3% of the money is actually printed, and 97% is made up by banks to earn interest on non-existing money.

I found 1attackerpKQNRBrmzhYkmoofg9nWeNC2 a few weeks ago. It sounds so unfriendly to use, but it is too rare not to keep (8 years for 50% chance on my system).

Apoorvlathey already said it, if anything else --help gives the options. Although oclvanitygen does not give this option, so ./vanitygen --help gives this option but it works anyway in oclvanitygen.

This giveaway is still open.

This is exactly what makes their service completely worthless. If someone gives me a cube of gold, I do not have to trust that person. While bitgold claims you own real gold, it turns out to be nothing more than a number they can charge back.
