If asked by people which coin is the most profitable what will we answer Of course BTC even though the title of the OP post above describes Bitcoin is difficult to understand but that answer is not a bedtime story, of course. BTC has everything we need in terms of investment and profit. It's just that its volatility is generally taken into account by many people and this type of long-term investment too.
OP should start from the beggining - no looking at BTC as an investment tool, but how it was envisioned to be.
Then he can start to go into different territories, such as investment, as we said.
Or simply shift his mindset, if he will think that Bitcoin is difficult to understand then it will be hard for him. But if he thinks that it's very easy because a lot of us understands it, then it will be not as difficult as it is.
And then he can go and move from that, maybe start slow and just be a short term holder.
When he got the experience already, then move to a bigger picture, long for Bitcoin as a long term investment and then imagine what it will bring to him, i.e financial freedom.
Its easy to understand bitcoin all you need is to think of it as gold the more demand and a limited supply the price will eventually go up but the major difference is that bitcoin is a digital currency where as gold can be physically handled. And bitcoin is very easy to operate with online gold that not everyone can purchase due to the availability and nature, but everyone can buy bitcoin in sats and hold to receive a percentage of profit when in the bull market. I think anyone who fails to understand bitcoin is because they don't want to learn, not because they learnt and could not understand but because they don't want to learn. I have read so many blogs about bitcoin as a beginner and watched several YouTube videos and trust me even a child can understand based on the explanations.
