I was one of them and I told that to everyone that took the time to listen and some of them did. A lot of my friends bought bitcoins at the all time high, believing that the price would skyrocket to $20 000 or even $50 000 per coin. As you know this did not happen and the price dropped with more than 80%. Since then a lot of us Bitcoiners became the laughingstock and the butt of the joke for the people who were too scared to take the risk. I hope we can prove them wrong and that we can turn this around in 2020 and have the last laugh, but I hope this is not too late for the majority of my friends who are holding on with the tip of their fingers. 
This can happen when we became so overeager or very excited about something, and we use our word-of-moth power to promote something even if we are not paid doing so or nobody told us to do it. Nevertheless, we owe a lot to people like you who in one way or another made Bitcoin as popular as it is today. What happened after the ATH in 2017 was something that many wide-eyed and zealous Bitcoiners never predicted to come and now we already learned our big lessons. Neophytes as we were then, we jumped into something with both feet and many even burned bridges believing that Bitcoin can be their financial savior. However, right now, I would say that there is a mild Bitcoin renaissance and if you were lucky enough to had entered Bitcoin when the price was still below $2000 then its current price of $7500 is not bad at all, compared to other investment vehicles available in the market. We are then hoping that come December 2020 we can say that this is a very good year for Bitcoin indeed!
