Bitcoins kaufen lohnt sich

Essentially, when you “mine” bitcoins, what your computer is doing is performing many complex hashing calculations that resolve the transactions in the system. Without miners, no bitcoins could be exchanged.

To bootstrap the currency and “create” bitcoins to be traded, every so many completed calculations rewards the miner who completes it with a bonus (originally 50btc). The number of computations to reach “magic block” is inversely related to how quickly these computations are being resolved. Mining is a zero sum game, throwing more hashing power at the network gives you a chance at a bigger piece of the pie at the expense of everyone else gunning for that “magic block”.

After every so many of these blocks of coins are created, the reward is halved. Currently, a bitcoins are created in blocks of 25btc. With 30$ US = 1 BTC, this currently forms the impetuous for “mining like crazy”. In fact, I’m pretty sure the quick rise of the value of BTC against the USD has a bit to do with that halving of the reward, at 12$ US = 1 BTC, you’d have to have a pretty efficient rig just to break even on electricity in most places.

Also, when a particular “miner” solves a “block” that resolves a transaction, they get credited with any “transaction fees” offered to speed up the transfer of coins from one address to another. Typically, transactions that pay higher transaction fees are resolved first. Eventually, those “transaction fees” will be *the only reward for mining*. This probably creates a vast need to expand the user base.

The idea is: by the time the “magic blocks” stop paying out vast amounts of bootstrapping BTC, the the vast increase of computing power + widespread adoption of bitcoin would generate transaction fees of enough IRL worth for miners to continue mining.
