Is Bitcoin the greatest scam in history?

Scam shouldn't be used as a label for Bitcoin at large, but the hype machine and pump-and-dump schemes around Bitcoin are most certainly teetering on the lines of being a scam. Bill Harris, former CEO of Intuit and founding CEO of PayPal and Personal Capital, writes: Promoters claim cryptocurrency is valuable as (1) a means of payment, (2) a store of value and/or (3) a thing in itself. None of these claims are true. Means of Payment. Bitcoins are accepted almost nowhere, and some cryptocurrencies nowhere at all. Even where accepted, a currency whose value can swing 10 percent or more in a single day is useless as a means of payment. Store of Value. Extreme price volatility also makes bitcoin undesirable as a store of value. And the storehouses — the cryptocurrency trading exchanges — are far less reliable and trustworthy than ordinary banks and brokers. Thing in Itself. A bitcoin has no intrinsic value. It only has value if people think other people will buy it for a higher price — the Greater Fool theory.

Stripe is ending their Bitcoin support

For Stripe, Bitcoin isn't scaling well to make it "useful for payments," and it's expensive in both time and money to process transactions. However, Tom Karlo said "Bitcoin has evolved to become better-suited as an asset rather than a means of exchange." A line in the sand has been drawn for Bitcoin as a useful payment currency. Therefore, starting today, we are winding down support for Bitcoin payments. Over the next three months we will work with affected Stripe users to ensure a smooth transition before we stop processing Bitcoin transactions on April 23, 2018. Clearly the value of Bitcoin is still there as an asset. It's just not working out (for Stripe) as a means of exchange for payments. Though they remain optimistic. Despite this, we remain very optimistic about cryptocurrencies overall. Tom also provided some insights to where things are heading for crypto and payments. We may add support for Stellar (to which we provided seed funding) if substantive use continues to grow. It’s possible that Bitcoin Cash, Litecoin, or another Bitcoin variant, will find a way to achieve significant popularity while keeping settlement times and transaction fees very low.

Zenbot

a command-line cryptocurrency trading bot using Node.js and MongoDB. This is on version 4, so a boat load of effort has been invested in this tool. In light of that, I find this statement from their README funny and somewhat sad: Zenbot 4 is functional, but is having trouble reliably making profit. At this point, I would recommend against trading with large amounts ...

Bitcoin Could Cost Us Our Clean-Energy Future

If you’re like me... ...you’ve probably been ignoring the bitcoin phenomenon for years — because it seemed too complex, far-fetched, or maybe even too libertarian. But if you have any interest in a future where the world moves beyond fossil fuels, you and I should both start paying attention now. We should be paying attention because the energy usage behind Bitcoin is astounding. What they might not have accounted for is how much of an energy suck the computer network behind bitcoin could one day become. Simply put, bitcoin is slowing the effort to achieve a rapid transition away from fossil fuels. What’s more, this is just the beginning. Given its rapidly growing climate footprint, bitcoin is a malignant development, and it’s getting worse. Today, each bitcoin transaction requires the same amount of energy used to power nine homes in the U.S. for one day. The aggregate computing power of the bitcoin network is nearly 100,000 times larger than the world’s 500 fastest supercomputers combined. The total energy use of this web of hardware is huge — an estimated 31 terawatt-hours per year.
