As Bitcoin sees a stratospheric rise over the last few days, increasing by $100 in just a day, users have noted a corresponding increase in transaction confirmation delays.
More than 250,000 bitcoins were waiting to move at one point yesterday, according to tradeblock, currently valued at almost $200 million. Tradeblock’s mempool, which tracks confirmation delays, reached an all-time high (ignoring last summer’s capacity tests) of 45MB. Tens of thousands of transactions and hundreds of thousands of bitcoins continue to be stuck for hours or days.
Bitcoin users took to reddit en-mass to complain and seek information. At one point, the whole front page was covered by the topic with seemingly new Bitcoin users asking for help. Some, however, maintain that the hundreds of millions of dollars’ worth of Bitcoin are all just spam or, in some way, some sort of attack.
