Ethereum Just Gained 30% on Bitcoin in 2 Days—Are Altcoins About to Explode?

Troller Cat ($TCAT) is an Ethereum-based meme token that blends humor with serious mechanics. This isn't just a meme—it's a movement.

In the rapidly evolving landscape of cryptocurrency, where new trends and technologies are constantly emerging, certain tokens have managed to capture the attention and interest of investors worldwide. As May 2025 kicks off, the question on everyone's mind is whether altcoins are about to explode, paving the way for massive gains and financial transformation.

The past year has seen a substantial recovery in the altcoin market, with Ethereum showing a remarkable 30% gain over Bitcoin in just two days. This surge has ignited fresh FOMO (fear of missing out) across the market, with retail investors eagerly searching for moonshot opportunities. Meme coins have also returned to the spotlight, not just for the laughs but for the real financial gains they offer.

Among the firestarters in this altcoin revival is Troller Cat ($TCAT)—an Ethereum-based meme token that blends humor with serious mechanics. The project, themed around history's most iconic trolls, is now in Stage 4 of its 26-stage presale. And get this: anyone who entered Stage 1 has already seen a 72.8% ROI. Those jumping in at Stage 4 can expect a jaw-dropping 6,044.68% ROI at listing. That's over 60x gain potential based on the listing price of $0.0005309. This isn't a meme—it's a movement.

Let's examine the 8 Best Cryptocurrencies for Passive Income that South American investors, especially those in Brazil, Chile, and Argentina, should watch closely this month.

1. Troller Cat ($TCAT)

Troller Cat isn't just trolling the internet, but the financial system. With 26 presale stages, each themed around legendary pranks (Stage 4 is called "War of the Worlds Broadcast - The Alien Invasion Troll"), this Ethereum-based token is built for virality and financial growth.

The mechanics are solid: The stage 4 price is $0.00000864, and the listing price is locked at $0.0005309, giving investors a 6,044.68% projected ROI—more than 60x in potential upside. For reference, a $1,000 investment today would yield over 115 million tokens, valued at $61,446.37 when $TCAT lists.

What sets $TCAT apart isn't just price action. The deflationary Game Center is where ad revenue fuels monthly token buybacks and burns. Every time someone plays a game and watches an ad? Tokens get burned, reducing supply and creating automatic upward pressure on the price. Combine that with 69% APY staking and a 2-year liquidity lock, and you've got real fundamentals behind the meme.

This coin hits home for many in South America who work long hours and still struggle to break even. Imagine someone working at a call center six days a week just to afford rent and groceries, still drowning in loan repayments. A $1,000 well-placed into Trollercat could flip that script. It won't happen overnight, but it gives a real shot—something traditional finance hasn't.

Why did this coin make it to this list? Because it blends meme magic with honest mechanics. With staking, burns, and a historic theme that resonates, $TCAT is one of the Best Cryptos for Passive Income right now—and a 60x opportunity like this doesn't knock twice.

2. Non-Playable Coin ($NPC)

Non-Playable Coin is precisely what it sounds like—unapologetically internet. Built on the Solana chain, $NPC takes the concept of background characters in video games and turns it into a crypto experience where everyone feels like the main character.

What makes $NPC interesting from a passive income perspective is its staking rewards and social missions. Users earn additional tokens by holding $NPC and participating in governance votes, meme contests, and in-app missions. These aren't just gimmicks—they're gamified utilities that create real community stickiness.

Its circulating supply is capped, and scarcity becomes a factor with burn events tied to community milestones. After a viral campaign, the token saw a 17x spike earlier this year, and developers continue rolling out updates with meme culture integrations.

Why did this coin make it to this list? It's not just passive income—it's participatory. For investors who want a coin that rewards engagement and makes memes meaningful, $NPC deserves a serious look.

3. ApeCoin ($APE)

Born from the Bored Ape Yacht Club empire, $APE already has mainstream reach. But it's also pivoted into real utility, including staking pools, DAO voting, and NFT-based passive income models. With big-name partnerships
