The problem with Bit Coin, and all cryptos, is that they are nothing but a Ponzi scheme where people are looking to sell it to the next guy for a higher price.
Have you even researched about bitcoin? Isnt it that people only uses bitcoin to scam? Knowing that bitcoin is a currency, it will never be a ponzi since it is only used as inveyment and you need not to misguide people to buy the product but let you decide yourself on how much you invest or buy. What ponzi do is misguide those people with lowly mind and want to earn easily, and ponzi is a doing of people with scam mindset. So before you accuse make sure you have researched everything and stop throwing false accusation to something you dont know!
