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.
Your investment in bitcoin at the moment is very good. But I think you should not invest your money at the same time. You should divide the investment into each wave because the bitcoin price may continue to go down.
people that buy while it post made maybe suffering loss now.while price drop alot its not means price is cheap to buy.there will always drop continuation until market oversold.using chart analisys help us to avoiding nasty transactions
