From all what you made mention, you are correct but some places you totally made reference to Bitcoin trading.
You made mention of investing in Bitcoin to earn profit, yes and absolute correct.
You made mention of Bitcoin investment requiring patience to hold, yes and correct.
You made mention of research, it's important as most newbies don't know when it is very suitable to invest. Yes, every Bitcoin entry price is profitable but by deploying some certain strategies one can get better portion than when being ignorant, so a close research is needed and not actually necessary, having someone to guide and pilot you during making investments, for maximum profit and security benefits.
However this hasn't always been the case as some tend to record more losses than profits and end up being far worse than how they started
This be the contradicting point, when dealing with Bitcoin investment, it is very difficult to loose funds from investing only on the condition of selling too early, meaning one lacks the patient to hold longer. Even investing from the pick dose not stop one from making profits as long he/she understands the cycle, there must always come a bull run reaching different all time high.
