Of course, to invest, you need sufficient knowledge because if you lack knowledge, the investment you make may lead to more losses. Of course, everyone doesn't want to experience losses, so if you really want to invest, you must have sufficient and good knowledge first. I myself am looking for learning. Just from this thread I think I can take some lessons from the many comments there are. Even though we may occasionally have to be brave enough to take risks, if there is a lesson that can be understood to minimize the risk then it is better to learn it, after all it won't result in a loss either.
Knowledge is good for investing in Bitcoin but beyond knowledge of Bitcoin and the underlying technology, one need to apply discipline and strategy to ensure that the investment is properly nurtured. If you really only on the knowledge of price movement, you will turn out to be a trader rather than an investor. As you know, trading is what require those highly technical and fundamental knowledge to make profits. As you know, this come with very high risk that one must be prepared to shoulder.
Restraining myself is not an easy thing, I still can't control my patience very well, I'm still preparing myself to be more ready to do everything.
If you are still facing these challenges, I will recommend you change your approach. I was in this stage before and leaning about the DCA method and other minor variations was what helped me. Now any fund I receive, the first thing I do is to set aside funds for my basic needs such as food, shelter, utilities and others, thereafter I will also keep some money aside as just for anything I did not plan for which might come up. My investment amount is usually calculated after I have settled these two items, this method help me not to sell my Bitcoin for any reason as the plan is to hold for a very long time.
If you employ this method of DCA and the adjustments I explained which I learnt from this forum, I'm sure you will have similar result which is a situation whereby you no longer panic or feel any FOMO instead you will feel relaxed irrespective of the market price.
