If they are greedy enough to think about big profits without even learning on what they are entering then their investment to bitcoin will be their worse experience since imagine if bearish run comes unto them and they don't know on what next action they need to do so once they lose in terms of losing its value for sure they will end up hating bitcoin for that reasons. That's the main reason that we should really need to learn more bitcoin and its usage or purpose they called so that we are fully ready to deal with the risk involve.
I'm also sure with doing all necessary measure we can make sure that we are ready to hodl since we already know how to settle up on our investment then start to aim for long term bullish trend that will possibly happen in future.
Some greedy people only think about making huge profits from bitcoin. But they won't be ready for what happens to bitcoin before its price rises. Even when the price falls further, they will not be ready because they do not have a strong hand in holding bitcoin. And when they have lost, they will turn away from bitcoin, hate it, and leave it. After all, it is their own fault for not wanting to learn more about investing in bitcoin.
