Bitcoin's price is "set for a massive bounce," according to cryptocurrency analyst "Crypto Birb." He believes the bull cycle's final move up will occur by the end of the year. The amount of bitcoin held by centralised cryptocurrency trading platforms has been continuously decreasing. Whales may be leading the accumulation, according to data, as wallets with 1,000 to 10,000 BTC now have the same amount of BTC as they did when the price was $57,000.
