hundred questions, the answer is still the same.
There are 2 perfect moments to buy BTC - in 2010 and today.

If you are a nocoiner now, now it's a good time to enter. At least for a try. Tomorrow and the day after tomorrow I'd answer the same, price will just be slightly different.
However, in the long term it won't matter.
Just like today it does not matter if you bought btc for 100$ or 200 in 2013
