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.

3 Things to Watch in Ripple’s (XRP) Price Today

XRP is testing the resistance at $2.3. Will it break?
Key Support levels: $2
Key Resistance levels: $2.3, $2.6, $3
1. Key Resistance Under Pressure
Yesterday, buyers pushed XRP to the key resistance at $2.3, but sellers returned to stop a breakout. At the time of this post, the price is in a pullback. Nevertheless, this is a positive sign that shows buyers are returning. If this bullish momentum intensifies, then $2.3 could fall and be followed by a test of $2.6 next.
2. Optimism Returns
With the price keen on making higher highs, optimism is returning to this cryptocurrency. This can be seen on the volume profile where buyers have dominated in the last few days. A break above $2.3 will likely see the volume spike and allow further price expansion into new highs.
3. MACD Turning Bullish
After the daily MACD turned positive last week, the 2-day MACD has also turned bullish today. This shows that the buy momentum is slowly creeping into higher timeframes which will build confidence in the price action and attract more buyers. With a positive feedback loop in action, XRP has a good shot at $2.6 or even higher in July.

Bitcoin Traders Wait Important Economic Announcements Today, These Altcoins Plummet (Market Watch)

Bitcoin’s price has retraced by a slight 0.9% in the past 24 hours as traders are expecting a few important economic events during today’s session.
Meanwhile, the broader cryptocurrency market is also reflecting the uncertainty as the majority of altcoins are trading in the red with some charting a lot bigger declines than others.
Bitcoin Price Waits for News
The deep involvement of corporate Bitcoin buyers and institutions has surely played a major role in its price increase over the past year but it’s also the reason why the crypto market has been largely correlated to traditional ones.
A few years ago, literally nobody cared about metrics such as CPI, PMI, and whatnot, but now every crypto trader has them on their watchlist.
As such, today is also shaping up to be a volatile experience with a few important economic events on the calendar.
First, Jerome Powell will speak in the afternoon, followed by data for job openings, PMI, and ISM manufacturing – all indicators that shape policymaking, especially when gauging the strenght of the local economy.
That said, Bitocin’s price is down about 1% on the day and is currently trading at around $106,500 after having tested $109,000 yesterday. It’s interesting to see if the bulls have it in them to push bakc towards the upper boundary of the recent trading range or if the bears will send the price back below $105K.
Altcoins in Red, Some More Than Others
As you can clearly see in the heatmap below, the altcoins are also not having a great day. This is, perhaps, to be expected – Bitcoin’s dominance over the market has been rising gradually over the past many months and whenever BTC slips, altcoins crash.
The past 24 hours have hardly been a crash, though, but it’s clear that most of them are charting more considerable declines.
This is especially true for TKX, ARB, SPX6900, SEI, and others, that are down between 8% and 15% on the day.
Believe it or not, Bitcoin Cash (BCH) is today’s best performer, gaining more than 6%. Who would have thought?

How Much You Should Invest in Bitcoin (BTC)? Veteran Trader Peter Brandt Weighs in

TL;DR
- The expert advises monthly investments in SPY and BTC for long-term success.
- The leading cryptocurrency is up 6% this week and trades near $108,000. Analysts are split – some see a breakout to $130K – $200K if key resistance levels are cleared, while others warn of a possible drop to $100K or even $95K if momentum fades.
‘Trading is the Wrong Path’
Besides its fundamentals and ability to transform the global financial system, Bitcoin (BTC) has proven to be an excellent investment opportunity.
At least, that was the case in the past few years: the asset went through multiple bear and bull markets to eventually cross the $100,000 mark. Currently, it trades at around $108,000 (according to CoinGecko’s data), representing a 75% increase on a yearly scale and a substantial 43,000% jump compared to its valuation a decade ago.
But does the leading cryptocurrency remain a good investment after this major rally over the years, and how much should people allocate to it? That’s a question many people are trying to figure out.
It seems that there isn’t a direct answer, and it all depends on the risk profile of the investors, as well as other important factors. However, one can turn to certain experts who are experienced enough to give guidance.
An example is the veteran trader Peter Brandt, who recently suggested that approximately 95% of people fail when trading. Instead, he advised them to excel in their regular jobs, prioritize their families, and invest in homeownership. Last but not least, Brandt recommended making monthly investments, allocating 80% of the amount to SPY (the ETF that tracks the S&P 500 Index) and 20% to BTC.

The Next Potential Targets
Let’s now take a closer look at BTC’s recent performance and explore its chances for a further pump in the short term. The asset has increased in value by approximately 6% over the past week, with numerous analysts predicting a surge to a new all-time high if certain conditions are met.
The X user Cipher X believes “a strong weekly close” above $107,720 could open the door to a further rally to as high as $130,000-$135,000 in Q3 2025.
“Just look at Q4 2024 chart and you’ll see what happened when BTC had its biggest weekly close,” they added.
Merlijn The Trader thinks the final pump for this bull run is coming, envisioning a fresh ATH of around $200,000 towards the end of the year. At the same time, he advised investors to take profits, anticipating a drastic pullback to $95,000 shortly after that.
On the contrary, Ali Martinez argued that the cryptocurrency currently faces a key rejection while the stochastic RSI flashes a death cross on the daily chart. The analyst thinks a plunge to $100,000 is not out of the question unless “we get a sustained close” above $109,000.
