Yes, it is worth commendable for this past 16 years, it has a very tough beginning, even from the time of my entrance into the crypto community in 2016, Bitcoin has actually overcome very difficult challenges. As at 2017, there were so many people that predicted that Bitcoin was a bubble ready to burst, there are those that said Bitcoin was a ponsi scheme, while others sees Bitcoin as a scam etc.
Time has gone by and Bitcoin is still going stronger, braking barrier, hitting All time High at different seasons, i must say that 16 year of Bitcoin existences is worth celebrating, even as I read on social media that President Donald Trump has done few days ago.
Finally, I am optimistic that the next 16 years is going to be massive pumps, mass adoptions, innovations etc. Bitcoin will be on the moon!
