While Bitcoin's price jumps around, some other digital currencies are making big moves. Among the top 100, four coins stand out for their impressive gains. These altcoins have seen increases ranging from 15% to 30% recently. Let's take a closer look at their potential next targets.

First up is AKT Coin, which has surged by 30% in the past day, now sitting above $6.2. Its value has grown by 50% over the week, reaching a market cap of $1.4 billion and a daily trading volume of $301 million. If history repeats and there's a sharp drop, it might settle around $4.3 or even $3.73.

Next, TON Coin has had a notable gain, rising by 18% to almost $7.1. Over the week, it's up by 31%, boasting a market value of $24.6 billion and a trading volume of $680 million. Breaking past $6.5 was a positive sign, and if it solidifies above $7.3, it could aim for double-digit prices.

GRT Coin is also making waves, with a 15% daily increase and an 18% weekly gain. With a trading volume of $210 million, it's eyeing resistance levels at $0.354 and $0.418, possibly even reaching $0.5 if momentum holds.

Finally, Arweave (AR) has seen a 15% jump to $44.23, with a weekly increase of 20%. Despite a lower trading volume of $200 million, its market value is nearing $3 billion. Breaking past $44.8 could signal a push towards $47.6 and $50, though caution is advised as previous attempts failed, leading to drops to $30.

In conclusion, while Bitcoin remains volatile, other cryptocurrencies are seizing the opportunity to shine. These altcoins show potential for further growth, but investors should remain vigilant amidst the market's unpredictability.
