Bitcoin ETF flows are expected to remain high leading up to the Bitcoin halving event later this month, according to Santiment, an on-chain analytics firm. Despite reaching an all-time high in mid-March, the volume of Bitcoin ETFs has not slowed down. Santiment speculates that this trend will continue until the halving event, which is estimated to occur on April 20. However, it remains to be seen whether there will be a drop-off in ETF volume and on-chain volume following the event. Lucas Kiely of Yield App suggests that the accumulation of Bitcoin through ETFs could reduce the likelihood of significant price swings after the halving. In March, spot Bitcoin ETF volumes reached $111 billion, nearly tripling the volume from the previous month. Recent data shows an increase in ETF inflows, with two days in April recording more than $200 million in net inflows. Grayscale, however, has consistently had outflows since converting to a spot ETF in January. Despite this, industry executives remain confident in the growth of the crypto market, with Ripple CEO Brad Garlinghouse predicting that the market value will double this year, primarily driven by spot ETFs and the Bitcoin halving.
