The amount of electricity required to mine Bitcoin will make it obsolete. There are more and better alternatives. The more people who come to this conclusion, and I believe that new people entering the cryptocurrency markets come to this conclusion much more quickly than people who had time to bond with Bitcoin in a less busy marketplace, the quicker will be the demise of Bitcoin. Only Bitcoin diehards believe in its primacy - it's a bubble. It's surging right now because if people buy it, they will get free Bitcoin Gold. After the November release of Bitcoin Gold, money will flood into altcoins. There are several coins I prefer to Bitcoin, including Dash.
