I believe it takes a million risk to invest in Bitcoin, still people are left with more than a million reason to take the risk. A lot of us especially the newbies are still skeptical investing, each with enough reason to invest and not to invest respectively. The core question here is; what triggers you to invest?...for myself, I haven't figured out any tangible reason why I should invest, solely because I'm yet to understand the nooks and crannies of the market fully. However, I'm working hard studying extensively to understand the market. I feel this great joy when one post his first time buying Bitcoin, I get this great zeal to buckle up and nurture the feeling of investing too, believing that one day, that which triggers the feeling to invest will come to manifestation. I envy every first timer Bitcoin buyer, cos I'm looking forward to being like them in no distance time.
Waiting to understand the concept of bitcoin is good, you will know what exactly you are doing, and you will get all the necessary ideas and risk management strategies you need.
I think only learning and understanding Bitcoin and how it works is enough reason for you to invest in bitcoin, you need to understand the concept of price movement and market strategy, that should be for people willing to learn about trading. All you need is to know about your bitcoin wallet, how to keep your private keys safe and how to buy and sell bitcoin that's all.
Be motivated by the uniqueness of bitcoin, do not invest because of FOMO.
