It's the year of Bitcoin in my opinion because after 2017 Bitcoin just moved flat in the market. In my opinion, the year of Dogecoin is not suitable, because there are still many other Altcoins that have increased positively since the middle of this year. We also don't underestimate Dogecoin which can surprise the market because they can always make a difference.
The year of Bitcoin was 2017, yes it has gone up many more times in the past but it was at a small market cap, and not many people in it. 2017 was when there was so much retail interest it shot up over 20x. And remember,,, this was when BCH threatened to wipe BTC out, and ETH also and both failed:)
For sure this is a good year,,, but going from 20k to 60k is not exactly a great year to top 2017
It could happen again and Bitcoin will peak this year. $63K already happened despite the previous low in early January of $29,374 and it looked like Bitcoin would sink by then. I'm sure Bitcoin has a great story this year and will be a year full of drama.
