You don't need any clear understanding before you start to invest in bitcoin, just invest by buying with your discretionary income, any knowledge you want to know will come along while you are investing. Every investment is a risk but bitcoin have proven to us over the years that it has long term sustainability but it's still good to evaluate possible risks that might come when investing so that it will enable you to make proper preparation in case a sudden change occurs.
You've provided a solid understanding for someone who may have been unaware of Bitcoin investing, even though they've been familiar with it for a long time. However, if we look comprehensively at every moment, from the past to the present, all investors should buy more frequently and consistently if they want to grow their portfolios. This way, they'll clearly see the potential profits without having to think too hard. As for risk, I believe it only arises when Bitcoin's price drops, but as long as we don't panic about what's happening in the market, everything will remain safe.
This is another dip to buy again because the price is rising again. and the price right now is $114+k and it is in the green and the indication shows that it will hit $122+k again, those who were waiting can invest now and don't waste their time again but invest now that is still low.
Now that Bitcoin's price is below $114,000, this is clearly a great opportunity for everyone to buy more aggressively, as Bitcoin's price won't stay this way forever, and even the indications you mentioned could reoccur in the near future. Because Bitcoin is already in high demand, it won't take long for the price to increase by the amount you mentioned.
