Not sure how much is the amount available to buy right now bitcoins but I am planning to buy them at a very lowest price. If there is possible that I can buy them at below $300 then this would be better.
Good luck,
But with halving close it is hard to believe that $300 it can be reached again.
bitcoin will surely not fall any more to such small prices as the halving event will make the people to buy more and more bitcoins right now as they will expect a big growth
to be honest i think that you should buy right now no matter what the price is right now, hopefully this will make all the bitcoins users a lot of money pretty soon
