I was buying till last week but to be honest I cannot afford to buy with the current price as price is too high for me, so If I want to buy then I will wait for the price drop.
You are not forced to buy a whole bitcoin. You can buy like 1/4 of the amount and you can grow it by the help of trading (altcoins) or just increase your bitcoin by joining different signature campaign 
.Maybe other people who are reading some of comments here are thinking to buy a whole bitcoin but that doesn't matter. Regardless how many bitcoins you are going to buy or even cent of bitcoin you are going to buy as long as you are able to buy with the current price that doesn't matter.
But we are just telling that the price today is not recommended for buying.
