When you send bitcoins, the transaction includes a reference to the transaction(s) in which you received the bitcoins to be sent. This is how the Bitcoin network verifies that you actually own the bitcoins in question. In other words, if you received BTC2, then another BTC3, and then BTC1, in three separate transactions, and you want to send BTC4, your new transaction will include a reference to two of your previous transactions. The more previous transactions are needed, the more data (in bytes) is needed to encode your transaction, and you are charged a fee based on the amount of data required. In practice, this means if you received a very large number of low-value transactions, and you want to send a high-value transaction, that transaction will require a large amount of data and will require a larger than normal fee, which may come as a surprise. The situation is roughly analogous to receiving a large number of pennies, then being charged a coin-handling fee when you take your sack of pennies to the bank.

Additionally, transactions sending less than BTC0.01 are considered "dust" and always require an additional fee, to discourage people from spamming the network with a large number of low-value transactions. You will not be able to spend any of your BTC0.002 without a fee; BTC0.0019 is the absolute maximum you will be able to spend (with a fee of BTC0.0001), though depending on the amount of data required for your transaction, an even higher fee may be required, and you will be able to spend correspondingly less.

Bitcoin is not designed for microtransactions. Bitcoin transactions are cheap, but not free under normal circumstances (and "dust" transactions are never free). If you have heard otherwise, you have been misinformed.

About 5 transaction are 1kb, so you will have to pay eytra fee for every 5 transactions included.

I actually have the v0.8.2-beta but i'm trying to understand this bytes thing, it's quite complicated >.<
So basically the more transactions i have in my wallet, the higher their size is and the higher the dust/transaction fee is?

That number is 5360 satoshis (0.00005360BTC)

Edit: Also, any transaction under 0.01 basically requires a 0.0001 BTC fee.

8.3 implemented the dust fee, which prevents transactions under a certain amount from occuring. this limit is called the dust fee. think its like 5150 satoshis( about .00005150 btc ) if you got your coins from going around to faucets, this indicates that there is so many bytes in yiour transaction(because the inputs are small and each small number of satoshis has its own tx hash, the size exceeds the maximum transaction size in bytes(network rule) .)

Hey guys, i've been using the Bitcoin-Qt client wallet for a couple of weeks and i have 0.002 BTC on it, and so i tried to make a small transaction and it's giving me an error stating that the amount to be sent is too low, any ideas please?
