In brief
- A new game based on the arcade classic Space Invaders will let one person earn a real Bitcoin reward.
- To claim the reward ,they must destroy 10,000 BTC worth of transactions that mirror actual activity on the blockchain.
- The winner will earn a 10,000 sats bounty, valued around $7.30 at the time of writing.
A new free-to-play Bitcoin game will pay someone a BTC bounty if they’re skilled at old-school arcade games, lucky enough to play while lots of Bitcoin is being transacted on the blockchain, or willing to move a ton of BTC to help grease the wheels.
In the web game Mempool Space Invaders, first spotted by Protos, players are challenged to shoot down Bitcoin “whales” that fall through the screen towards their ship. Each whale represents a real transaction on the Bitcoin blockchain, and upon being blasted by the player, it adds the quantity of BTC from each transaction to the player’s score.
Fail to destroy the whale and your shields will slowly deteriorate until you’ve lost the game. You can choose to start over for free—or pay 1,000 sats (about $0.73 worth of Bitcoin; each sat is 1/100,000,000 BTC) to continue your previous run.

Ultimately, the first player to destroy 10,000 BTC in the game—representing some $730 million worth of real Bitcoin transactions—will earn a bounty of 10,000 sats, or about $7.30 in BTC from pseudonymous developer Jasonb, per a Stacker News post from the creator.
Taking home the bounty though will require serious skill and luck. Players must shoot down all the whales, many of which fall simultaneously, making it difficult to stay alive for long. If you’re lucky enough, though, you might play while large Bitcoin transactions are taking place on the blockchain, allowing you to destroy larger whales and stack bigger quantities of BTC in a short period of time.
But there is another way to win, according to the pseudonymous developer—though it’ll require the ability to move a massive amount of crypto.
“The people’s approach,” said the developer in a post outlining the game, is to “throw up a 10,000 Bitcoin transaction to yourself and wait for it to show up.”
“Then blast it out of the water—er—space,” they explained. “Just make sure not to spend too much in fees, or you’ll eat up all your winnings.”
Of course, not everyone has $730 million in Bitcoin laying around to win the game. As an alternative, the developer cheekily suggested trying “two 5,000 Bitcoin transactions.”
“Just make sure that they are broadcast close enough together that you can shoot both of them in the same game,” they added in the footnotes.
If you don’t want to risk sending $730 million on the blockchain, you can try to play it out like some in the Stacker News comments, where one user said they were able to destroy a “paltry 70 BTC,” and another only 30 BTC after 20 minutes of trying. That won’t cut it.
Anyone that actually completes the initiative will need to share a screenshot of their “game over” screen to unlock the bounty. If they put in the “effort to fake that,” the sats reward is “deserved,” the game’s author wrote.
Other free-to-play games have offered users a risk-free way to stack BTC, but often the reward is not worth the time or effort. Most Bitcoin-backed games only offer pennies’ worth of BTC for each hour of play, and even then, you’ll have to endure loads of video ads to earn that pittance.
Bitcoin is up 1.3% in the last 24 hours, slightly increasing the game’s bounty in the process as it trades around $73,198. The top crypto asset has jumped more than 9.5% in the last week, but still sits 42% below its all-time high of $126,080.

BTC falls 0.49% in 15 minutes: fragile long leverage and active sell-off pressure resonate to weigh on the short term
From 18:00 to 18:15 (UTC) on 2026-04-17, the BTC price fluctuated and trended downward within the 77097.4 to 77573.2 USDT range. Over these 15 minutes, the return rate recorded -0.49%, and the amplitude reached 0.61%. During this period, market trading was active; short-term volatility was amplified, and trading attention increased significantly. The main driver behind this abnormal move is that the overall leverage structure is bearish and long positions are fragile. At present, the BTC perpetual contract funding rate has remained negative for 11 consecutive days, indicating that the bears have the upper hand in the market. In addition, futures open interest (OI) is about 628.3 billion USDT, which is at a historical high. During the anomaly window, trading volume increased noticeably. On-chain data shows large amounts of BTC flowing from long-term holder addresses to exchanges, suggesting that active sell orders may have triggered longs to passively reduce positions, amplifying downward price pressure. Moreover, institutional positioning enthusiasm in the mainstream contract market has cooled off; liquidity boundaries have tightened, causing large-trade activity to have an amplified effect on market volatility. In the options market, implied volatility rose to 39.81%, increasing demand for downside protection and reflecting a defensive posture among market participants. Macro-environment volatility and some capital flowing into safe-haven assets, together with the recent regulatory uncertainty-related historical events, reinforced the move, pushing overall market risk appetite lower. Current BTC leverage risks still remain. If, in the future, there are concentrated sell-offs, volatility may be further amplified. It is recommended to continue monitoring sustained high OI levels, the persistence of negative funding rates, and on-chain transfers of large amounts of funds, and to stay alert for whale behavior and any disruptions to market sentiment caused by macro-policy developments. For subsequent price action, please watch key support levels, institutional and whale on-chain moves, and relevant global market news, and guard against short-term risks.

BTC drops 0.45% in 15 minutes: Whale concentrated transfers into exchanges stack up sell pressure while leverage withdrawals amplify the pullback
From 17:00 to 17:15 (UTC) on 2026-04-17, BTC saw a brief drop. The return rate recorded was -0.45%, with the price ranging from 77354.3 to 77916.9 USDT and a swing of 0.72%. During the event, market attention warmed up, volatility intensified, and spot market liquidity changed significantly.
The main driver of this price anomaly was that whale wallets concentrated transfers to exchanges. In a single 15-minute period, the exchange inflow surged to 11,000 BTC, reaching a new high since December 2025. The average amount deposited per transaction was as high as 2.25 BTC, indicating that large holders chose key price levels to concentrate and release their positions, clearly lifting sell pressure. At the same time, BTC futures open interest fell to a 14-month low of $841 million, as leverage funds exited sharply. The spot market’s pull on price fluctuations became the main factor, further magnifying the impact of whale trading.
In addition, although ETF funds had a net inflow with a hedging effect—bringing the April cumulative inflow to $5.651 billion—within this anomaly window they were not able to fully absorb large sell orders. The spot market mainly relied on institutional buying to digest the selling pressure, and overall risk appetite contracted. On-chain data shows that 41% of the BTC supply is in a loss-making range, and some holders who bought at lower prices face take-profit and stop-loss pressure. With multiple factors converging, short-term tension formed among exchange inflows, leverage withdrawal, profit realization, and institutions’ ability to absorb, increasing the magnitude of spot volatility.
Short-term risks are worth watching closely. Users should closely monitor core indicators such as the subsequent exchange inflow volume, the pace of ETF net inflows, and futures open interest. If whale sell orders still have not eased and ETF inflows cannot accelerate in step, the BTC price may remain under sustained pressure. Users should focus on on-chain transfers and changes in major holders’ positions, watch the spot market’s key support ranges and trading structure, obtain more market information in a timely manner, and stay alert to risks brought by sharp volatility.
