Blockchain is going to survive as a supply chain technology. It will be very important for reacting to food borne illnesses.
Seriously? You think that's the only thing that people can do with blockchain technology?
Cryptocurrency/bitcoin is an idiotic asset bubble mania product that will replace "tulips" in the vernacular for bubbles
The fact that people can't differentiate between Bitcoin and cryptocurrency in general is part of what inspires comments like this one.
Crypto might be overvalued at the moment. It's exceptionally difficult to know what will be the true market value of something as vast as Ethereum. Ethereum alone could eventually handle the entire transaction volume of SWIFT, Visa, Mastercard, and AmEx once they've moved to the PoS model with sharding and a complementary offchain solution (Plasma or Raiden). And that's before you factor in other applications, private blockchains based off Ethereum, etc. How much is ETH worth? Do you know?
XMR is currently the "darkcoin" of choice. Great for evading the law/IRS and other fun stuff. And how much is XMR worth?
You can't do any of those things with tulips.
Bitcoin has failed in its original mission to be "digital cash" as described in Satoshi's whitepaper. BCH will fail that mission once any significant number of people try using it. Ethereum will get there eventually, though it won't be ETH tokens you use as money (you might wind up using stuff like
DAI. IOTA might actually be the long-term winner if they can ever get their act together (IOTA isn't even a blockchain; it uses
tangles).
People like Sarah Jeong who think cryptocurrency is "digital beanie babies" can't see beyond the hype. That makes her no better than the people trying to buy Bitcoin at $19k. The first goal (and just the first one, mind you) of blockchain tech is to vastly improve the efficiency of existing payment/currency networks. No more SWIFT, no Paypal, no more cumbersome (and often insecure) proprietary payment networks. Instead you will get near-instant transfer of wealth to any part of the world for pennies (and thanks to stuff like PoS, no more running tons of ASICs/graphics cards to secure the network). People today are betting on which technology will win out in the end, or at least make a significant contribution to the future of payment networks and other blockchain-related efforts. Visa/Mastercard/AmEx are putting quite a bit of resources and doing quite a bit of hiring to address this matter; why do you suppose that is? Are they all caught up in the hype, too?
Problem is that many investors do not understand cypto at all. There's a great deal of "stupid money" pouring into the sector. After the S2X debacle, most people should have pulled out of Bitcoin anyway (as well as all its forks), but they didn't. Shows you that the crypto market is infested with a great deal of irrational behavior and territorial thinking.
The important thing to remember is that the meritorious projects with lots of skilled developers behind them haven't even reached version 1.0 yet. None of them are fully-functional at this time. Except Bitcoin. With Bitcoin, what you see is what you get (don't give me that LN/RSK nonsense). Regardless, people are investing a lot of money in unfinished products. The people putting their money in crypto right now are visionaries, gamblers, or suckers. You can't just hold up the suckers and claim the entire thing is a scam.
