We're definitely getting there and exchanges (Binance, Poloniex, etc.) closing registration because they can no longer handle more users is a proof of that. I say we give bitcoin one more year, after that, almost every service will be in the process of adding it as a payment method (assuming that we will have LN stable and working by then).
A lot of us are really banking on Lightning Network (LN) to be working for Bitcoin as the situation right now is not working right for the future of Bitcoin as a currency. Yes, there is no problem with it as a store of value but this is not the way Bitcoin should be. There are some businesses which already dropped Bitcoin because of the perennial issues affecting the coin and something must really be done. As to stage of adoption, yes, I think we are getting to be there but as we have seen things will never be walk-in-the-park there will always be bumps and humps along the way. Is cryptocurrency really the future like what many are saying it is? We hope so despite the noise coming from FUDs affecting the overall sentiment of the market.
