    Exchanges are being targeted by 51% attacks. If you're running an exchange, you need to read the blog post below. Many tokens are designed to take advantage of exchanges that don't read the fine print.

    Some exchanges (, ) stopped trading ERC-20 tokens because a bug can allow attackers to create new tokens arbitrarily, and manipulate prices. Here's a reminder from over a year ago, that some ERC-20 tokens added such backdoors on purpose.

    Question for security token lovers: what happens when an exchange holds for its clients 10% of Apple’s “shares on the blockchain”, and a rouge exchange employee steals the keys? Does that employee now own 10% of Apple, and y’all just go on with your lives?

    Cryptocurrencies optimized for payments are like Snapchat. Sure, you can have some success, but the best outcome is that traditional systems use their network effects and copy your features, destroying the value of your asset. It’s a terrible long-term strategy.

    Once Twitter/Instagram are forced (sadly, that's what it will take) to remove all fake/bot/inactive accounts, many "influencers" are going to be caught with their pants down (re: follower counts) I, for one, can't wait for that day

    回覆給 @stephanlivera
    The nice thing about “payment maximalism” is that it gets the people going... By creating competition, you force the incumbents to adapt and improve their existing systems. But this mostly played its part by now, and it’s not a good long term strategy for any asset.

    Anyone saying unconfirmed transactions are “secure” is either lying or stupid. If you disagree, show me *one* exchange that accepts unconfirmed deposits, of any size, no matter how small. Just one.

    So was never really a DEX. Calling it such is totally misleading, it was actually one of the least decentralized relayers. It only allowed order execution through its own address in order to facilitate matching.

    The highly educated researchers at (a blog for iotards) say that Eric is a charlatan. You should follow Eric.

    1. Be me 2. Work as cryptocurrency lead & financial IT company 3. Research cryptos 5. Research IOTA dumpster-fire, avoid like the plague 4. Do tests on BTC+LN, ETH, Eris & Hyperledger instead 6. IOTA fans: Omg Eric doesn't like our coin because conflict of interest! Charlatan!

    Going after PoW coins is wasteful. There’s a much bigger, lower hanging fruit: ERC-20 tokens. Many are complete shitfests. Remember, ERC-20 is an *interface*. Implementation is left as an excercise to the issuer. Yet exchanges assume they’re as secure as PoW coins. Boom.

    Recently, interviewed Verge’s on his shitcoin, which imploded yesterday. Here are the tough questions Ran asked. “Are you private?” - oh yeah! “Can you get to visa-scale?” - oh absolutely! “Are you guys really decentralized?” - Oh for sure! 1/5

    ARE YOU KIDDING ME?!?! A tiny island nation in the Pacific Ocean is going to create a brand new currency for their citizens with 24 million units, and they are giving 12 million units of that currency to a start-up company from Israel. What the fuck.

    Did your favorite Twitter personality tell you that will see shitcoin market caps reach new heights? Did they tell you that blockchain is eating the world? Congrats, you now know where the noise is. Unfollow that fool, and welcome bear Twitter.

    I’m not trading because I suck at it, so I’m hodling on. But I am now proudly fundamentally bearish. It is overwhelmingly clear to everyone with half a brain that this industry is 90% hot air, and soon it will be clear to the brainless as well. You know it’s true
