Cardano price analysis

As stated, a spike in whale purchases has commonly indicated the largest price shifts for the DeFi asset in the past. Just over a week ago, Finbold reported evidence Cardano whales were accumulating after a 7-month dumping spree.  After a period of seven months during which whales had dumped a total of 1.7 million tokens, the data revealed that Cardano whale addresses that own between 1 and 10 million ADA had been stocking up their wallets with 196 million more ADA over the last five weeks. Given that the Vasil hardfork is scheduled for June with the intention of expanding the protocol and significantly increasing its transaction throughput, volume, and liquidity, whales may be anticipating a rise in the Cardano price, as historical data indicates that the price of ADA often increases prior to a hardfork. Currently, Cardano is trading at $0.545, up 19.26% in the last 24 hours and down 30.53% across the last week, with a market cap of $18.4 billion, over $4.3 billion more than the $13.97 billion from which it had when it bottomed out around $0.40 on May 12, according to CoinMarketCap data.
