Bitcoin is a p2p system of transaction. Bitcoin has shown alot of signs so far that it is here to stay and even over Shadow the normal system of transaction.
And bitcoin is the only 'means of first transaction' among users without the need for intermediaries and costs to be incurred. So this makes horror for banks in most countries, and no doubt politicians and the government move to reject it without thinking about the benefits and positive effects it brings. Even if they contribute to help develop their existence, I think there will be extraordinary benefits or income they will get, both for the people and their banking.
Bitcoin which was created in 2009 by sir satoshi Nakamoto it growth level is quite OK and the value is still volatile and prone to changes of the market
Since the beginning of 2017 the price of bitcoin has increased by 1300% (very volatile) as more and more consumers come in droves to bring hope of making a profit from increasing popularity and associated increases in the value of bitcoin. So bitcoin will forever fluctuate regardless of how big and small the level of fluctuations will occur.
