Do you think that 2017 was the "Golden Year of Crypto"? Or is the best is yet to come? Your input will be greatly appreciated.

We can't say that 2017 is the "Golden Year of Crypto", as we are at the very beginning of the development of crypto. I am sure that there will be many more surprises in the future, which will be associated not only with the price of BTC. but also the appearance of new altcoins that will attract attention.
I agree with you, because 2017 was the year when cryptocurrency became famous, therefore many investors are interested to investing in cryptocurrency and make the price of cryptocurrency increase very high in 2017, so I also believe that in the future there will be unexpected things about cryptocurrency and make cryptocurrency famous again, so that the price will increase very high and exceed the price of cryptocurrency in 2017.
