Yes now would be a good time to buy, even with the volatility. Buy the bitcoins for the long term, 3-5 years.

Also what do you want to do? wait until it goes higher before you buy? You want to buy while its cheap. Bitcoins are only cheap when there is fear in the market and trust me, now is a once in a life time opportunity especially with all the hack attacks. Lots of fear in the markets so it will force people to dump their btc IN THE SHORT TERM.

Remember, btc as a currency is still fundamentally sound. The btc hasn't been breached at all. The only thing that has been breached are a couple insecure websites. Those websites are important to btc in the short term only. There are a bunch of exchanges that are opening up. So in the future if one website is breached it will be no big deal because there will be 10 others to use.

Remember this. The best time to invest are when there is blood in the streets. The best time to sell is when there is gold in the streets.

What this means is simply: buy when there is fear in the market and prices are low. Sell when prices are high and optism is high.

Now is the buying opportunity of a lifetime. You don't want to pass it up.
