I just hope bitcoin price become stable. around 10-15k is perfect for me. If you still want bitcoin replace fiat money
What is the point if bitcoin price become stable? Bitcoin a trading/investment asset, if the price is being stable for too long time then I'm afraid people will start to leave it because stable price = less profit in term of trading.
Bitcoin price will never stable imho and it wont replace fiat money forever. I do not even hope it will replace fiat money, I guess many others also hope the same with me. I will only agree if bitcoin is just an alternative payment of fiat money.
For now yeah the situation around didn't support Bitcoin to have a mass adoption and used widely as a payment tool , Bitcoin more popular considered as an investment/digital asset. No wonder it's hard to expect bitcoin would completely recognized as a currency, 2018 might could be a year to keep hitting the new ATH.
