Bitcoin (BTC) whale buying and selling in 2023 is mostly from speculative investors, new data reveals.In the latest edition of its weekly newsletter, “The Week On-Chain,” analytics firm Glassnode shows that contrary to popular belief, opportunistic entities are the most active whales.The birth of the Bitcoin “short-term holder” whaleSince BTC price action returned to $30,000, a shift has taken place among Bitcoin traders.As Glassnode shows, so-called short-term holders (STHs) — investors holding coins for a maximum of 155 days — have become significantly more common.As it turns out, the largest-volume investor cohort, the whales, is also composed of large numbers of STHs.“Short-Term Holder Dominance across Exchange Inflows has exploded to 82%, which is now drastically above the long-term range over the last five years (typically 55% to 65%),” Glassnode states.“From this, we can establish a case that much of the recent trading activity is driven by Whales active within the 2023 market (and thus classified as STHs).”Bitcoin short-term holders dominance of exchange inflows (screenshot).
