Chainlink emerged as one of the best cryptocurrency performers on Sept. 6 as the price of its LINK token jumped 8.25% against the U.S. dollar.The LINK/USD exchange rate reached $36.35 for the first time since May 20, months after bottoming out near $13.45 — thus recovering by more than 170% altogether. At the same time, its recent bout of buying saw prices bringing in about 36% month-to-date returns.Ecosystem growthOptimism Ethereum announced on Sept. 1 that it had integrated Chainlink’s market-leading decentralized oracle solutions to its Ethereum layer-two services. As a result, LINK — which serves as a payment and staking token inside the Chainlink ecosystem — rose by 36% on the prospects of seeing higher interim demand from Chainlink users.The same fundamentals previously assisted LINK investors in closing 2020 at a 540% profit.A booming decentralized finance (DeFi) space and its dependency on Chainlink to secure live data feeds pushed demand for LINK higher among users and speculators alike. As a result, Chainlink’s market share in the DeFi reached 80% at one point in time, reported ZDNet.How Chainlink works. Source: ChainlinkLINK continued its climb in the first quarter of 2021, surging 161%, but followed the upside boom with a disappointing second quarter after falling 37%. Its losses came in the wake of an overall correction trend across top cryptocurrency tokens, including Bitcoin (BTC) and Ether (ETH).Yuriy Mazur, head of data analytics at crypto exchange CEX.IO, said LINK could climb above $50 in the coming three weeks. The analyst cited Chainlink’s partnership with over 76 new projects in August as one of the primary bullish indicators for its native token. He told Cointelegraph:”This relevance has perhaps boosted LINK accumulation to access the Chainlink offerings. As a result, spot traders appear ambitious to stir the price growth until LINK/USD retests the previous all-time high of $52.”But for Stephen Tuttle, a financial analyst at Seeking Alpha, the next big upside target for Chainlink’s token sits near $65.Tuttle noted that traders have allocated all their attention to Ether due to its principal involvement in the booming nonfungible token (NFT) space. As a result, he anticipated a capital reallocation after the ETH price rally tops out, which would be extremely beneficial to the LINK market.”If Chainlink can once again reach 0.02 Eth per Link, at Ethereum’s current price, this would place the Link token at about $65, or a 2.6x increase from its current price of $25.”At the time of writing, the LINK/ETH rate was 0.009 ETH.Broadening wedge alert!LINK’s latest price rally also surfaced in the wake of an overall crypto boom, with Bitcoin retaking $51,000 and Ether rising toward $4,000. Crypto traders raised their bids across the board, anticipating that the Federal Reserve would delay its taper plans after two disappointing U.S. jobs reports last week.Related: Chainlink (LINK) looks for momentum while pro traders target $40As a result, LINK’s market bias remains highly correlated to top coins. Atop that, there are hints that the token is seeing the formation of a bearish reversal indicator, as highlighted in the chart below.LINK/USD daily price chart. Source: TradingViewDubbed an “ascending broadening wedge,” the indicator showcases two rising bullish trendlines that deviate from one another. The pattern does not warrant buying exhaustion but points to sellers’ ambition to take over each time the price touches the upper trendline.As a result, LINK/USD still holds the potential of undergoing a large pullback toward the lower wedge trendline (around $28). Nonetheless, bears would need to close below $37.96, the 50% Fibonacci level of the Fibonacci retracement graph drawn from the $52.32 swing high and $13.61 swing low.
