Great article that should be read by anybody who wants to buy some bitcoin or other crypto currencies. The main take away is to use the DCA method to take advantage of the volatility in the market. I have been buying bitcoins since the start of the year myself, and its so much better to spread out your purchases across multiple months instead of buying everything at once. Who would have thought in January that bitcoins are going to drop down to 17,000 USD. The timing issue is one the biggest challenges in trading and with DCA we need to worry less about buying at the right price. Also DCA is well used strategy in stock trading for years.
