It will depend different factors, like the price. I buy sometimes when the price is low, and if I have available money to spend it on btcs. If the two factors are good enough, then I can afford to buy some coins...
yes that is good, but i think still the price of bitcoin is so good for buying, as it is expecting that the price of bitcoin will increase too much in next few months so i think if some one is interested in bitcoin then they should buy bitcoin in present price because it is still good time for buying and you will not be able to get such an opportunity.
