Buy now as early as possible, Cause bitcoin price now is low, Then sell it after halving. That was only my opinion 
I believe it the time has come that a lot of people are waiting it. because now bitcoin is in hightest price and i think it is good for us, also that halving is coming after 46 days. So wake up and ready to get profit and enjoy your life.
But secondly bitcoin's journey is not finish in this time, it will be continuously live with us, and we always use it and invest it.
