To me, the biggest flaw of bitcoin is that you have to constantly spend energy on it (as in computation power &amp;#x2F; burn coal) for it to remain viable. As soon as enough people get tired of throwing away money at their miners someone can pull a 51% attack, so everyone must put more energy into their miners to protect their investment... forever.&lt;p&gt;Over time the amount of energy wasted by bitcoin could become stupendously dumb. We could be using our spare processor cycles to fold proteins or aid in numerous other research, and yet we&amp;#x27;re using it to allow people to send bits of data to each other without a need for centralized trust.&lt;p&gt;Compare that to the centralized bank where you have a single centralized trusted source which allows transferring money from one person to another to take no more energy than a modest server and some backups -- far less than the power consumption of a single GPU miner.&lt;p&gt;The above problem also won&amp;#x27;t get better. Even after you&amp;#x27;re no longer mining for new coins, you must keep up the mining volume to protect existing coins and allow transactions to occur at all. I personally find the above to be a fundamental problem with the &amp;quot;proof of work&amp;quot; solution. Sure, on paper you&amp;#x27;ve solved the General&amp;#x27;s problem, but the reality is that you&amp;#x27;re throwing massive amounts of energy out the window. Because of that, I think this proof&amp;#x27;s place should have been to remain on paper.</text><parent_chain><item><author>tribaal</author><text>Yeah, as much as I like the concept of bitcoin (and the blockchain), I don&amp;#x27;t see adoption becoming anything more than anecdotal.&lt;p&gt;No interest rate, and you have to secure it yourself?

I&amp;#x27;m happy to pay some transaction fees (&amp;quot;extortion!&amp;quot;) to get that kind of insurance.&lt;p&gt;Bitcoin is the electronic version of &amp;quot;let&amp;#x27;s buy a lot of gold and stash it somewhere&amp;quot;.&lt;p&gt;EDIT: Burn karma, burn.
