Yes this is the good time to start buying Bitcoins. Buying more Bitcoin will grow in the future. As if its price increase in the future bigger profits will come your way.
I am advicing to buy now a lot of bitcoin because the price or the value of bitcoin now is very low and really affordable and buying many bitcoin now is really advisable to do because bitcoin price in the future can really pump up to $30k.
personally i am prefer to wait until bitcoin price reach $5500 .while price goes down sharply dont ever think its cheap for us.there will more falling until it hit strong support in chart.
