5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
ancient mining can be traced back to the selection of stone materials in the stone age. Later, with the rise of the metallurgical instry, mining, mineral processing technology has graally developed. This paper introces the ancient Chinese open-pit mining, underground mining, roadway support, rock fragmentation, roadway ventilation, lighting, drainage, transportation, mineral processing and other aspects< There are many surface outcrops, slope deposits or resial deposits in open-pit mining of various metal veins or orebodies, so open-pit mining has become an important mining method in ancient times. Open pit mining can be divided into excavation method and reclamation method
2. Mining is the synonym of accumulated income for activities in bitcoin

trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data
the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
