According to WhalePanda's monitoring, Bitfinex whales have been accumulating BTC for most of the bear market. As prices began to rise in November last year, they started selling some positions. Then, after the ETF was approved and a large amount of GBTC flowed out, they began to accumulate again at the end of January. When the price rose to $70,000, they started reducing their positions more aggressively. Now, every sell-off is below $62,000 and whales are slowly but surely accumulating again. It is estimated that about 300-400 BTC are accumulated each day which almost entirely covers newly mined bitcoins (450 BTC every 24 hours).
