we have only 5 months to get in 2019, I don't think that crypto can do it , but in less than 4 years maybe.
Indeed ... 2019 is only in 5 months but everything is faster in the crypto world and when BTC was pumping hard everyone was talking about crypto.
So if BTC hit a new ATH, maybe we will have a (mass ? ) adoption and after it will be mainstream.
But it will take 2 or 3 years.
