I don think that buying bitcoins right now is the option because i know for sure that when you want to buy bitcoins you have to wait a bit longer wait till the price is down and then you can see the rael price of the bitcoin off course.
If you are a long term holder then you can buy even at current price as in long run price probably would be higher in compare to present price so if you have managed to hold higher volume of coins then it will surely benefit you and will give you higher returns as most of the people are putting money in bitcoins only because they think that its an best investment for future.
