    Why is this happening, anyway? And is it just a slump, or is the bubble actually bursting?

    Worth remembering Jensen did state that he saw Crypto revenue going forward to be flat or reducing allowing a return to focus on gaming albeit with the caveat that crypto mining segment is highly volatile in terms of supple/demand.
    But then his statements do seem to swing a lot each month lol; in February stated looking forward in 2018 flat to decline for crypto mining, then maybe a month ago I think he mentioned crypto mining-blockchain here to stay however maybe context is slightly different POV between each of his statement as he did not see it has a primary-core revenue driver for Nvidia.

    Makes one wonder if part of the delay for next Geforce models is to tie into the crypto mining slump to keep the revenue-growth narrative strong, or at least contributed to strategic decision along with component-BOM pricing,logistics, the ideal product cycle window from a business perspective; part of such a decision process though would also hold back Quadro/Tesla so *shrug* although they have the V100 versions for now.

    Bitcoin Gold, a hard fork from Bitcoin, suffered from a 51% hashing attack from an unknown hacker.

    Although that particular crypto wasn't very strong at all and not that much money was lost (only $18 Million were reportedly lost), it brought the attention to everyone about the dangers of a centralized cryptocurrency.

    And since Bitcoin itself is heavily centralized on Bitmain (a chinese mining company), everyone became aware that Bitcoin is a lot more fragile than it was generally thought.
    So Bitcoin suffered its monthly crash and all other cryptos followed, as usual.

    Bitcoin Gold unfortunately shares an algorithm which is also used by a much larger coin ZCash (which is the original user of the algorithm IIRC). Zcash's total nethash is about 20 times more than BTG. That means it's relatively easy to find a lot of hash power out there to attack a smaller coin. However, the attack is not cheap, it's been estimated that the attacker spend ~0.12BTC per minute to rent enough hash power for the attack. Of course, the attack is still hugely profitable.

    Also it's actually not about "the dangers of a centralized cryptocurrency," quite the opposite. it shows the danger of huge number of smaller coins, as those smaller coins are not as secure as the large coins (which is, ironically, similar to the case of sovereign debts...). It could drive people to the larger coins and make it's much harder to sell smaller coins (which IMHO not a bad thing).

    One big problem with the current PoW system is, unfortunately, most "miners" are just doing the hash, not the validation. Therefore, it kinds of invalidate the idea of PoW, because those miners are just printing tickets for a much smaller number of real validaters, and it's those validaters who have the potential to disrupt a blockchain. That's why there are various PoS schemes being proposed.
