    In the Cryptocurrency Era, Approach Used GPUs With Caution



    We’ve written a number of articles on the current lousy state of the GPU market and what you can practically do about it, ranging from optimization guides for existing cards to whether AMD’s Ryzen 5 2400G can serve as a plausible low-end gaming solution to tide you over if you need a new card. But there’s another option available — the used GPU market. Does it provide a reasonable alternative?

    The short answer is: Maybe. But you’re going to want to be extremely careful before you pull the trigger.
    The problem with buying a used GPU off an unknown seller is that you’ve got no idea what the card’s operating conditions were. While this has always been true, cryptocurrency mining puts unique stresses on GPUs compared with conventional gaming.

    First, cryptocurrency miners typically run 24/7, while most gaming GPUs don’t. Gamers also tend to understand and prioritize good cooling, while cryptocurrency miners tend to maximize performance first and worry about cooling later. Four GPUs that are perfectly capable of cooling themselves individually can run extremely hot when put loaded into a chassis at the same time. GPU miners may also have overclocked a GPU or tweaked its voltage for stability. While this is also a risk when buying a used gaming card, again, we’re talking about the difference between 24/7 operation and occasional use.

    eBay offers certain protections to guard against being sold defective equipment. But just because hardware works the day you receive it doesn’t mean it won’t fail in a month or two, or display erratic crashes when loaded in a very specific fashion. We recommend buyers looking for a used card prioritize owners who specifically state that the GPU has not been overclocked or used for cryptocurrency mining.

    Still, this advice relies on the original owner being honest. What can we do to avoid relying on the owner’s honesty?
    Simple: We can test the card. But in order for the tests to be effective as diagnostic criteria, you’ll need to test your current GPU first.

    It’s common to see people recommend benchmarks like Furmark for GPU stress testing, but I’m going to disagree with that assessment. AMD and Nvidia both scan for thermal viruses like Furmark and typically prevent them from pushing GPUs as hard as possible. Instead, I’m going to recommend you run your tests in games you already own, either by looping built-in benchmarks or with play-through tests.

    Cryptocurrency Miners Bought $776M in GPUs in 2017



    New data on the GPU market has put formal numbers behind the visible impact of cryptocurrency mining on GPU prices. Unfortunately, we’ve also got fresh information suggesting the GPU price inflation cycle isn’t ending any time soon.
    Jon Peddie Research has released data on GPU sales in Q4 2017 showing that GPU shipments decreased 1.5 percent in Q4, in-line with normal seasonal expectations. Year-to-year GPU shipments decreased by 4.8 percent, driven mostly by declines in laptop shipments (desktop dropped 2 percent, but notebooks fell 7 percent).



    AMD’s market share rose by eight percent from Q3 to Q4 2017, suggesting an explanation for why Vega and Polaris chips are so over-priced (we noted this in our coverage earlier this week). If cryptocurrency miners are preferring Vega over Nvidia’s Pascal, it would explain why prices on AMD cards are blown sky-high — it reflects increased demand for those parts. JPR notes, “Over three million add-in boards (AIBs) were sold to cryptocurrency miners worth $776 million in 2017. AMD was the primary benefactor of those sales.”

    Ethereum Chart Set to Roll Over, Ripple on the Verge of a Breakdown

    Ethereum ‘head-and-shoulders’ developing on right side of topping pattern

    Bitcoin and other Cryptocurrencies-ethusd-d1-metaquotes-software-corp.png


    The cryptocurrency space looks headed lower soon, with a couple of charts holding set-ups of intrigue given the posturing and price levels in play. Ethereum (ETH/USD) is sporting a pattern inside a pattern, while Ripple (XRP/USD) is showing little buying interest at key price support.

    A break of the neckline and support zone (800/770) should kick off the next leg lower and further cement the broader topping pattern. Looking lower, there is trend-line support from November, then below there the 200-day MA, and Feb low at 565. The major target objective, though, lies near 400, where the apex of the wedge from late last year lies.

    Popular Cryptocurrency Exchanges Slash Bitcoin Transaction Fees

    Bitcoin and other Cryptocurrencies-btcusd-d1-metaquotes-software-corp.png


    Bitcoin transaction fees is cheaper now, as three of the most popular cryptocurrency exchanges have slashed their withdrawal fees rates by up to half. Binance, Bitfinex, and Kraken have enabled SegWit (Segregated Witness), a process to increase block size limit, and capacity to add more transactions. Transaction batching is another method being adopted to help them significantly reduce fees.

    Bitcoin Weekly Analysis

    Bitcoin (BTC) Price Chart Highlights Heavy Losses

    Bitcoin and other Cryptocurrencies-btcusd-w1-metaquotes-software-corp.png


    Five bearish lower high/lower low candles in a row this week emphasize the current weak state of cryptocurrency heavyweight Bitcoin. Not only has BTC broken through support offered by zone one and two, it has also re-entered the downtrend from the December 17 high of just $20,000. And to add to the bearish outlook, the 78.6% Fibonacci retracement level at $8523 was broken, although BTC currently trades back above this level. Support currently around $7,600 – the bottom of the downtrend – ahead of $6,000, the February 6 low print. On the upside, BTC will have a cluster of resistance levels between $9,300 and $11,600 to break and close above before the chart begins to look positive.

    Bitcoin Struggles To Stay Above $9,000 As Traders Wait And See

    Why has Bitcoin been having a hard time staying above $9,000?

    Bitcoin and other Cryptocurrencies-btcusd-d1-metaquotes-software-corp.png


    The world's largest digital currency approached $9,500 earlier today, but quickly gave up these gains, falling below the $9,000 mark several times, according to the CoinDesk Bitcoin Price Index (BPI). Bitcoin fell to as little as $8,860.87 today, representing a roughly 6.5% decline from the day's high of $9,474.86, additional BPI figures show.

    "There is a lot of uncertainty in the market right now, since there has been little guidance about resolutions to the impending regulatory actions by US agencies," said James Song, founder and CEO of blockchain startup ExsulCoin.

    Charles Thorngren, CEO of Noble Alternative Investments, also weighed in on how regulatory developments are affecting digital currency markets.
