- At least two major bitcoin exchanges reported cyberattacks this week.
- The attacks were 'denial-of-service' in nature and did not affect clients' funds.
- Bitcoin briefly more than tripled for the year when it topped $3,000 last weekend.
Multiple cyberattacks on major bitcoin exchanges this week highlight the many challenges for the young digital currency world.
A surge in investor interest also overwhelmed major bitcoin websites, while record-breaking levels of fundraising for new digital currencies add to worries that the largely unregulated cryptocurrency industry will be unable to manage the hype.
"Investors with assets on centralized cryptocurrency exchanges should be careful. The track records of these organizations are not good, and as the assets on the exchanges grow, so does the bounty for attacking or hacking them," said Benjamin Roberts, co-founder and CEO of Citizen Hex, a digital currency trading start-up backed by three Canadian venture funds.
