So what are your inputs now?
Unpredictable and none was expecting elon would be bought billions of doge coin directly from binance. It seems dogecoin has prove some of us wrong. Nobody predicted this coming I guess.
Now, if this happened to Doge will Shiba Inu have the same fate after 4 years?
People have been under estimate this meme coin and they were getting surprised after billionaire was shilling for that and bought bunch of doge coin from the market. Now, if this happened to Doge will Shiba Inu have the same fate after 4 years?
For me, unfortunately I sold my 10m Doge before the real bull run happened. So lessons learned I guess not yet the time for me to be be crypto rich. But, I will not fall to that same mistake again with Doge that I never listened to my instincts.
I have been sold 30 millions of doge coin a few years ago and that's my biggest mistake. It worth a lot of money today. i can buy a few lambo with it. 
As you said that mistake learned and move on. Now my new bet is on Shiba Inu. Some might say nay like my responders from my former thread but still I will hold to it like my dear life. I still love Doge like I used to in 2017 but Shib might be the instrument that will change my life forever.
Almost all of people who didn't get into the doge train was moving to the next train on shiba inu. This time shiba inu was almost entering into the top 10 CMC. that means if those who have been joining in the shiba train has been making big money from there.
