Bitcoin / Mining speculation / I know it's too late, but aren't we shooting ourselves in foot by buying ASIC?

Buying ASIC miners goes against the common good. It give an individual the upper hand for a while until most miners upgrade to ASIC. By that time, a 5Ghps miner will give the same a amount of bitcoins as a 200Mhps GPU miner gave 6 month before.
In the long term, we all loose and the only winners are the ASIC manufacturers.
This is a fine example how group behavior eventually goes against the common good.
But I guess it's too late for that now... the hash rate snow ball is rolling faster and getting bigger by the minute.

היום יש FPGA של ALTERA בטכנולוגיות של 22nm. הם אמנם יקרים בטירוף אבל נותנים ביצועים לא רעים בכלל לעומת ASIC בטכנולוגיה של 65nm כי על אותו שטח סיליקון יש פי 10 יותר שערים לוגיים.
אם אתה רציני, תתחיל עם FPGA מהדור החדש. המעבר מ- FPGA ל- ASIC הוא יותר קל. מה גם שזה פחות מפחיד משקיעים כי אתה יכול להראות תוצאות תוך כמה שבועות. לפתח ASIC מהתחלה זו השקעה מינימלית של 4 מיליון דולר, לא כולל עלות שכר מהנדסים.

Economy / Trading Discussion / Re: As a store owner who accepts bitcoins, anyone who wants can track my income

If I generate addresses on the fly for each transaction, this mean I have to save the key to each address on the server. For many small business the use shared hosting, security will be a major issue. And even if I have an address for each transaction, one can still figure out how much I am selling. I will have to turn those coins into fiat money in some market. So I will have to transfer them to some main address... If I generate the addresses offline, it solves the security problem. But I don't see a way to hide my income from a determined "spy". Bitcoin may be anonymous, but its open ledgiure blockchain may eventually kill it.

Economy / Trading Discussion / As a store owner who accepts bitcoins, anyone who wants can track my income

I decided to accept bitcoins in my online store only to realize that anyone who wants can type in my wallet address into the block explorer and see each and every transaction made to my address. This way, anyone can know hoe much money my business is making. Today I obviously keep this data secret and never publish sales data...
Isn't that a HUGE reason for businesses not to accept bitcoins?

Isn't it in the best interest of the network that each block will contain as many transactions as possible? Why make transactions wait? If it takes the same effort to create a block with 10 transactions or 1000 transactions, why the system does not enforce choosing the the latter?
Theoretically, a node which has considerably more computing power vs the rest of the network, can choose to include 1 transaction with each block, deliberately delaying confirmations (or controlling them) since it has the biggest chances of finding a new block...
