Best Cryptocurrencies to Invest in Today

1. Chainlink (LINK)

LINK is currently trading at $19.88, with a 6.79% increase in the last 24 hours. The trading volume of the coin has increased by 87.99% to $1.21 billion, while the market cap stands at $13.48 billion. The coin is up 24.05% on the weekly chart and 56% on the monthly chart.

Chainlink is showing a clear bullish trend on the daily chart. The price has broken above the $19.87 resistance level. The next major resistance lies at $25.41. If Chainlink breaks this level, the next target is $29.20. This move would represent a 47.16% gain from the current price.

The previous resistance at $19.87 could now act as a support zone. This level is key to maintaining upward momentum. If the price drops below it, the bullish trend could weaken. However, the current momentum remains strong. As long as Chainlink holds above the current support zone, the outlook stays positive.

2. Litecoin (LTC)

LTC is trading at $119.81, a 3.41% increase in the past day. Its trading volume has increased by 5.08% to $1.64 billion, while the market cap stands at $9.11 billion. In addition, the coin has gained 24% and 42% on the weekly and monthly charts, respectively.

Litecoin is showing a strong upward momentum. The price recently surged from the $90.80 support level. This bullish move confirmed strength above the key support zone. Litecoin is now facing resistance around the $123.00 zone.

Would like to see a base form above $105 here. Ideally some compression or flag before attempting the break.

LTC is approaching a potential consolidation before a breakout. If the price breaks above the daily block, it could target $143.00. This level marks the major resistance and high of the current range. However, if the price fails to break $123.00, it may retest support at $100.00.

3. Polkadot (DOT)

DOT is currently trading at around $4.56, with a 3.77% increase in the past day. Its trading volume has increased by 54.12% to $452 million, while the market cap stands at $7.29 billion. The native token of the Polkadot blockchain has gained 31% in the past month.

Polkadot has formed a falling wedge pattern on the weekly chart. This setup mirrors the 2020 breakout, which led to a strong rally. The price now holds above a key support zone near $4.00. This level has acted as a base since mid-2022.

$DOT is the next 10X play. ✍️

The falling wedge shows a breakout attempt, signaling a possible trend reversal. The next resistance lies around $8.00. If the price clears this zone, it could accelerate towards $12.00, supported by innovative technology and a growing ecosystem.
