In Bitcoin I think it's easy, just invest in the long term with a large amount then it is very likely that you will get a big profit, I think we can make it simpler and of course knowledge is also important but I don't imagine that it is more needed than trust in investing in Bitcoin.
I don't know how to you got the idea of investing in Bitcoin with a large amount of money and expect huge profits because you sound like someone who will scare away beginners and people who has little amount to start with because they will feel that investing in Bitcoin requires huge amount of money which is not true, anyone can start making investments with a disposable income they have and not necessarily a huge amount of money.
That's another wrong misconception of people since they falsely think about that you need to put huge money instantly before you get huge profit for your investment done with bitcoin. That word just invest large will create confusion to people and maybe they might get discourage then think about bitcoin is for rich dude since they can't afford to invest since it needs huge amount of money. That's why it need to be corrected and any amount will do so that we could create or do friendly approach and motivate lots of people to invest bitcoin with long term.
Instead thinking about profits they should focus to build their portfolio, since its good to take care their accumulation rather than imagining their profits to take which is for now we can't really get the exact figure. So much better to pay attention on more important things like how to make everything goes smooth and successful.
