Is Doge Losing Steam As Traders Choose Pepeto For The Best Crypto Investment?

The post Is Doge Losing Steam As Traders Choose Pepeto For The Best Crypto Investment? appeared on BitcoinEthereumNews.com. Crypto News 17 September 2025 | 17:39 Is dogecoin really fading? As traders hunt the best crypto to buy now and weigh 2025 picks, Dogecoin (DOGE) still owns the meme coin spotlight, yet upside looks capped, today’s Dogecoin price prediction says as much. Attention is shifting to projects that blend culture with real on-chain tools. Buyers searching “best crypto to buy now” want shipped products, audits, and transparent tokenomics. That frames the true matchup: dogecoin vs. Pepeto. Enter Pepeto (PEPETO), an Ethereum-based memecoin with working rails: PepetoSwap, a zero-fee DEX, plus Pepeto Bridge for smooth cross-chain moves. By fusing story with tools people can use now, and speaking directly to crypto presale 2025 demand, Pepeto puts utility, clarity, and distribution in front. In a market where legacy meme coin leaders risk drifting on sentiment, Pepeto’s execution gives it a real seat in the “best crypto to buy now” debate. First, a quick look at why dogecoin may be losing altitude. Dogecoin Price Prediction: Is Doge Really Fading? Remember when dogecoin made crypto feel simple? In 2013, DOGE turned a meme into money and a loose forum into a movement. A decade on, the nonstop momentum has cooled; the backdrop is different, and the market is far more selective. With DOGE circling ~$0.268, the tape reads bearish-to-neutral for the next few weeks: hold the $0.26 shelf on daily closes and expect choppy range-trading toward $0.29–$0.30 where rallies keep stalling; lose $0.26 decisively and momentum often bleeds into $0.245 with risk of a deeper probe toward $0.22–$0.21; reclaim $0.30 on a clean daily close and the downside bias is likely neutralized, opening room for a squeeze into the low-$0.30s. Source: CoinMarketcap / TradingView Beyond the dogecoin price prediction, DOGE still centers on payments and lacks native smart contracts; ZK-proof verification is proposed,…
