1. Have knowledge about Bitcoin.
No rush, take your time learn about Bitcoin, how e they work en underlying technology ( Blockchain), the risk and rewards way they inside also learn about wallet ( where them they store Bitcoin) where and how you fit exchange them, the measure way you fit take secure your wallet.
I don't think one need to go this deep before starting his bitcoin journey (investing in bitcoin), just having th basic knowledge, and how one can secure his asset he or she is good to go . Because the time one is taking to focus on accumulating knowledge alone when he or she should also be accumulating bitcoin, may lead to one missing out big time. Because the price wait for nobody now alot of folks are even saying that Bitcoin is too expensive, but as time goes Bitcoin will get to a point where people will refer this recent price as when bitcoin was cheap.
So as one is learning about Bitcoin, expecially in this forum is advisable that he or she is also accumulating Bitcoin or holding some stashes of Bitcoin while learning more about Bitcoin, so that as Bitcoin continue to surge In price your stash will also surge with it.
