Yes you are correct odolvlobo, there's no connection between Bitcoin and Ponzi scheme anyone saying Bitcoin is a Ponzi scheme don't understand how Bitcoin works, in a Ponzi scheme you will be told to invest and after you invest you will be receiving your return weekly or daily but Bitcoin investment is totally different you invest and you keep holding till you see that it has gotten to a price you wish them you can sell and make your profit, in Bitcoin investment you are the one doing everything yourself and you are the one to know when the profit is okay for you to take no second party.
I have been scammed before through Ponzi scheme, someone told me about an online investment platform and when you invest you will get profit every 3 days not knowing is a scam I invested and after 2 weeks they started paying me the profit and then I decided to double my profit and that is where I started having issues and I lost everything.
Bitcoin is not anything like Ponzi scheme.
