Vitalik Buterin answers critics of PoS

- Swan Bitcoin managing editor Nick Payton said that any PoS-based cryptocurrency is secure.
- Vitalik Buterin called Payton’s statement a lie.
Ethereum co-founder Vitalik Buterin criticized the statement of Swan Bitcoin managing editor Nick Payton, who said that any cryptocurrency whose operation is based on the Proof of Stake consensus algorithm is in fact considered a security.
“Dear Proof of Stake adherents, the fact that you have the opportunity to vote on any changes is a confirmation that you are dealing with securities,” Payton said.
Vitalik Buterin called such a statement an outright lie.
“Some PoW proponents just keep repeating the blatant lie that PoS includes voting on protocol parameters (it doesn’t, just like PoW). Nodes reject invalid blocks in PoS, just as they do in PoW. It’s not hard,” Buterin wrote.
Buterin also mockingly corrected Payton’s “grammatical errors.”
“In English, when it comes to Proof of Stake, we don’t say ‘it’s a security,’ we say ‘it’s safe.’ I understand that these suffixes are difficult, so I forgive the error.”
Proponents of Bitcoin and the Proof of Work consensus algorithm have long criticized Proof of Stake, calling the technology more centralized. In Proof of Stake, the owners of the coins, not the computing power, are responsible for the stability of the network. Concentrating many coins in one hand can lead to centralization. Proponents of PoS, on the other hand, rebuke PoW supporters for the blockchain’s inefficiency and slowness.
This is not the first time Vitalik Buterin has spoken out in support of PoS. Earlier this month, for example, he responded to bitcoin maximizer Jimmy Song, who argued that PoS does not provide a decentralized consensus because it does not solve the problem of Byzantine generals.
“If there’s a long tradition of people arguing between A and B based on deep arguments about mathematics, economics and philosophy, and you come in and say ‘B is dumb because of a one-term formality involving definitions,’ then you’re probably wrong,” Buterin replied.

Bitcoin Price Recovers $3K, SUI Rockets 10% to $4: Weekend Watch

Bitcoin’s sudden nosedive on Thursday evening and most of Friday has finally stopped as the asset bounced off and recovered three grand from bottom to top.
The altcoins are also well in the green today, with ETH jumping back above $3,700 and SUI marking a notable double-digit surge.
BTC Reclaims $117K
The primary cryptocurrency was in a consolidation phase since July 14, when it hit a new all-time high of over $123,000. In the following ten days or so, it remained sideways around $118,000, with a few brief attempts for a breakout in each direction.
The buyers and sellers managed to maintain equilibrium for a while, but the bears took control on Thursday evening as Galaxy Digital began disposing of massive portions of BTC. In a matter of hours, bitcoin’s price tumbled from over $119,000 to a two-week low at $114,500.
After dumping by more than four grand, the bulls finally reemerged and didn’t allow a further breakdown. Just the opposite, BTC bounced off and jumped past $117,000, where it stands as of press time as well.
Crypto analysts believe this could be a pivotal moment if it manages to maintain above this level, as it could open the doors for fresh ATHs next week.
It’s very clear; if #Bitcoin can hold above $116.8K, then we’ll start to see new highs in the coming week. pic.twitter.com/jC0Gpg9db7

Alts in Green
The altcoins experienced substantial losses at the end of the business week but have reacted well today, with notable gains. Ethereum is above $3,700 once again after a 3.5% daily jump. XRP defended the $3 resistance and is now at $3.15.
Solana, HYPE, XLM, LINK, and BCH have charted even more impressive gains, while SUI and HBAR are up by double-digits. The former has tapped $4, while the latter is above $0.26.
The top performers from the largest 100 alts include ENA (17%), SPX (14%), and SKY (13%). The total crypto market cap has gained roughly $70 billion since yesterday’s bottom and is up to $3.940 trillion on CG.

Whales Bought the XRP Dip While DOGE Hits Key Accumulation Zone: Details

TL;DR
- Ripple’s native token was among the poorest performers during the Thursday and Friday market crash, dropping below $3 after the recent all-time high.
- This has allowed large investors to buy the dip, while Dogecoin’s surge today has pushed it back to a key accumulation zone.

Recall that the third-largest cryptocurrency posted a new all-time high at the end of last week when it finally broke above the 2018 peak of $3.4 and surged beyond $3.6. However, it started to retrace in the following days, which culminated on Friday with a slip below $3.
This came amid worrying moves by Upbit, longs getting crushed on Binance, and a reported sell-off of $140 million worth of XRP from one of Ripple’s co-founders.
Nevertheless, the cross-border payments token managed to remain above the crucial $3 resistance and has recovered some ground to $3.17 as of press time. This dip didn’t go unnoticed by large investors, as they have accumulated over 130 million tokens in just 24 hours. From a USD perspective, this stash is worth roughly $400 million.
Meanwhile, the crowd became a lot less greedy in regard to XRP (and BTC), which could be considered a bullish signal.
When it comes to DOGE, the popular analyst Ali Martinez said it has returned in a “range that has historically served as a buying zone, triggering major bull runs.”
He further noted that DOGE has to reclaim the $0.25 resistance, which would be a “huge win.” If it does, then the path toward $0.36 will be cleared with “almost zero resistance.”

Is This the Ultimate Bullish Signal for BTC and XRP?

The cryptocurrency market experienced some turbulence at the end of the business week, with multiple assets dropping by up to 10% from their local peaks.
BTC and XRP are no exception. Both dropped hard, driven to an extent by FUD from large sell-offs. Now, though, Santiment has outlined a big bullish sign.
BTC, XRP to Reverse Trajectories?
Remember Warren Buffett’s wisdom about investing – buy when others are fearful and sell when they are greedy? This narrative has been particularly impactful in the cryptocurrency market, where greed and fear often dominate investors’ thoughts.
Santiment has also been a massive proponent of the thesis, and the company’s latest post highlights the recent changes in investors’ behavior. According to the overall social dominance, it determined that BTC and XRP have dropped out of the greed zone, even though both registered new all-time highs just last week and are currently trading close below them.
This is mostly because BTC dumped from over $123,000 to under $115,000, while XRP slipped from $3.65 to just below $3. However, Santiment said markets tend to move in the opposite direction of what the crowd expects, which “actually makes BTC and XRP buy-low candidates.”
While Bitcoin & XRP are seeing low greed levels, Ethereum’s +147% gains since early April still has traders bullish. Markets move the opposite direction of the crowd’s expectations, which actually makes $BTC & $XRP buy-low candidates.

The same theory cannot be applied to ETH at the moment, though. The second-largest digital asset has soared by triple-digits from its April lows, and retail investors continue to be greedy, which might not be such a good sign for it.
Galaxy Completes Sell-Off
Perhaps driven by substantial sell-offs initiated by Galaxy Digital for a third party, BTC’s price slumped hard yesterday to a two-week low. However, Mike Novograz’s company announced late on Friday that it had successfully executed “one of the largest national bitcoin transactions in the history of crypto on behalf of a client.”
“Galaxy completed the sale of more than 80,000 bitcoin—valued at over $9 billion based on current market prices—for a Satoshi-era investor, representing one of the earliest and most significant exits from the digital asset market.”
With such a massive sell-off out of the picture and retail’s lack of greed for BTC, the asset could be primed for another leg up to and beyond its all-time high.
