Bitcoin can reach $100,000 in 2018 if there are no any significant obstacles such as government regulations against bitcoin.
The biggest obstacle is the government, or specifically bankers who lobbying central authority to ban cryptocurrency.
Even though Bitcoin has gained some support in the financial industry thanks to CME and Nasdaq, banking institutions are still not convinced.
Such as happened in Bulgaria where bankers have cracked down and shut down the accounts of exchanges and Deutsche bank issued market briefing and stated bitcoin will crash in 2018, Banks is the natural enemy of bitcoin.
Without a doubt, when Banks are giving 0.01% on investments accounts...and BTCitcoin is giving 900% it is not rocket science.
