Bitcoin is just like a ponzie pyramid schame today, your fund invested in bitcoin are vanishing because early adopters / merchants are selling / spending / cashing out them very hard (you saw all those " xxx accepted bitcoin" news, most bitcoins accepted are sold right away means your fund has been transferred to the merchants, Convert fiat to bitcoin -> use bitcoin to pay merchant -> merchant convert bitcoin back to fiat), they must thank you for your free money to buy: Luxury House/Yacht/Jet/Cash/etc, just like Charles Ponzi's old happy day, so wonderful

Only who bought lower than you will sell/use the coins, same as you want more people to buy the price higher than your bought price so you can grab their money and get rich just like a ponzie schame.
The question is people are getting out, no one is buying your coins, what you left at the end are worthless digital numbers but at least you had have fed many exchangers + payment service providers with "fees"
