Memecoins are rallying, with Dogecoin (DOGE) surging 50% and mirroring Bitcoin's (BTC) price movements. Meanwhile, the new crypto Rollblock has raised over $7.5 million in presale, boasting a 250% price increase and innovative revenue-sharing features, positioning it as a promising investment in the GameFi sector. As Bitcoin approaches new highs, analysts suggest DOGE could follow suit, but Rollblock's utility-driven model may offer more sustainable long-term growth.
