try blockchai.info i think they have some option for this. If you have a cellphone with android, you will see more options to buy btc, and maybe something more suitable for you.
EDIT: try https://www.virwox.com/ they accept paypal

The cost you are talking about are for massive production right ?
I think OP was talking about building just a prototype for personal use.
It wouldn't have to be miniaturized (one can easily find some square meters to put a miner if it is profitable).
I know nothing about ASICs, I just read the wikipedia page, and I am not good in electronic either, but mining algorithm aren't secrets.
Would it be so hard to build a mining chip with basic electronic components ? (I guess the answer is yes, else someone would already have done it)

No, with basic electronic components you cannot achieve any significant speed, and also you will need a warehouse to put your circuit XD. You need to use integrated circuits, as you are likely going to use millions of transistors.
There is a first payment that is the same whether you make 1 or 1 billion chips.
You technically can, you just need tons of money and knowledge (or even more money to hire people with knowledge)
To explain better, an ASIC is a specific integrated circuit you design and fabricate.
For making one, you will usually need a team of engineers working full time, you need specific software like Cadence that costs a fortune on license.
Once you go to fabrication stage, that is the most expensive part, because you need to go with a foundry (usually TSMC) and pay millions of dollars to get in production.
From the foundry you get wafers with many chips inside, which you have to dice, package, and test.
Then the chips go to a board with connections and cooling system.
Design phase may take up to a year. Fabrication takes 1~3 months.
I'm not sure about the cadence license, because I have free access in my lab, but I've heard the full suite is like $100k per year. The mask set for fabrication in TSCM 65-nm is about 2 million dollars and each silicon wafer has a price of $10k each.
Anyway, here I'm trowing at you some numbers I have in my head, some may not be very accurate since I'm student to I have all the above for free, but basically, if you want to make ASICs, you alone can't, you need to create a start-up to raise the funding necessary to cover all the expenses.

Thanks for the interest in my post.
Last night I was playing with the idea before going to sleep and I thought to post it in here.
It's actually my first post in a forum without being trolled by somebody XD
Hi bitcoinbitcoin113, I like the simulations you've done, nice work

Hi all, there is a method for gambling in the roulette that allows you to almost always win. The trick is that you need to have a lot of money to start with.
The idea is simple: bet to color (black or red), which has nearly 50% change of win and payout is 2x. Every time you lose you double your bet, and if you win, you start again with the original bet.
So, suppose you bet 1, lose, bet 2, lose, bet 4, win, you win 8 and spend 7, so you still win 1.
There is a mathematical formula for this which is not that hard to understand. Suppose you bet 'x' and lose n-1 times in a row, winning in the n-th time. What you win is x*2*2^(n-1) and what you spend is the sum of n bets, which gives x*(2^n - 1). The profit is then x*[2^n - (2^n - 1)] = x.
Losing 7 times in a row has a probability of 0.7%, and you need to spend 256 times you original bet. So, if you have enough money in your hand, unless you are extremely unlucky you will always win something.
Now, when applied to bitcoin gambling, let's name satoshidice, you have to consider also the transaction fee.
Going back to the previous example, with n-1 loses and winning in the n-th time, you have to pay n times the fee 'f', so the total profit is x-n*f which should be positive.
If you bet the minimum, BTC0.01, and the transaction fee is BTC0.005 you will always lose because you spend more in transaction fees that what you can win.
Making 'x' 10 times larger than the transaction fee will give us 0.1% change of having negative profit (if playing to 50% change of winning).
You can avoid loosing with transaction fees while also betting the minimum if you change the multiplication base by another number, like 3. This way, the amount of winnings increases a lot, but you also need to have more bitcoins to spend.
If we revise the previous example, now multiplying by 3 instead of 2 in a losing, what we win at the n-th roll is 2*3^(n-1), and the total spending, including transaction fee, is (3^n - 1)/2 + n*f.
Total profit is then x*(3^(n-1) + 1)/2 -n*f. Because the winnings increase exponentially with n, even betting the minimum you will never lose.
Disclaimer: This is a mathematical analysis of the probabilities of winning in bitcoin based gambling sites. Whereas there is never 100% success of winning, using this method, and with enough money in your hand, you have high chances of winning. The more money you initially have the more chances you have of winning.

Hi, I'm new to LTC mining, I have a computer with an Nvidia GT620 (nothing big, but I just wanted to give it a try)
I downloaded reaper and set up the config files to mine ltc with gpu, using the Ozcoin ltc pool (http://newlc.ozco.in/)
First time I run it, after compiling the kernel the my screen went black and after a while all the windows started to appear again, one by one and quite slowly. Reaper kept saying error 6 can't connect to server and the stats shown like 8 GH/s which is weird because I know I should expect something in the KH/s range.
I checked the hots name, if I use http://newlc.ozco.in, I just get error 6 and nothing else happen, no driver unstability and it says 0 H/s, but if I change the host by newlc.ozco.in (without the 'http://') first it says "longpoll detected" and then just error 6, and the driver gets unstable, with my computer crashing some times.
Any clue on how to make it work?
Thanks

Hi, I'm having some problems with reaper.
I was trying to mine LTC instead of BTC to give it a try, but I found some problems.
First, I got an error 6, which it was apparently caused by using "hppt://" in the host name.
After this, reaper loads the kernels into the GPU, connects to the server (I'm using ozcoin), waits for a share and freezes the computer a couple of seconds later.
I was trying to google the problem, but the information I can get is scarce and mixed in other discussions.
Have any of you had this problem and solved?

I saw a new million satoshis page, but I can't understand much of that. I registered on the first one but got nothig.
Could you explain a little more how to get the credits?
