A lot of people told bitcoin is a scam, it is a Ponzi scheme from the beginning of Bitcoin creation! Who listened to them they are crying because they missed a golden opportunity to be something big! Many people were telling buy bitcoins as much as you can, who listened to them, they are now rich
Yes those people who believed in bitcoin as scam definitely will regret once price reaches to moon. We cannot force others to join right away in bitcoin. Almost coins drops so fast but probably the following year it will increase.
From many years ago, people always keep call bitcoin is scam but bitcoin always survive and the price growing more bigger. I am believe people who called bitcoin is a scam will regret because bitcoin price will reach highest price again and more.
