Also, an investor can never profit from Bitcoin for sure. Bitcoin is only a financial asset.
I beg your pardon...am I misunderstanding what you wrote, because the last time that I checked early invetors who bought bitcoin at $500 is in a massive profit. I don't want to use my bitcoin portfolio to tell you that I am already in profit because I start accumulating bitcoin in 2023 when bitcoin price was at $45k range.
I could remember when JJG was explaining how long term hodlers are making good profits than traders in the long run to someone on this thread and he used himself as an example that he has being accumulating bitcoin since when bitcoin price was $500, and that his average price of bitcoin at that time he was writing the post was $1k and by then bitcoin price was at $76k, meaning his portfolio has made 76x profit.
So first you need to understand the real potential of Bitcoin and make a long-term investment by doing proper research.
To get started as a new investor, all you need is the basic knowledge of bitcoin and your discretionary income to start investing immeediately. You can learn and make researches of whatever you want to know about bitcoin up your way as you are accumulating.
