Grayscale has continued their push for a spot Bitcoin ETF in the U.S. with the launch of a marketing campaign encouraging people to support their efforts for a Bitcoin ETF. The campaign started in Washington D.C. as an advertisement from Grayscale appeared saying “we care about crypto investors,” along with a QR code that takes you to the SEC website to submit a comment. The VP of communications from Grayscale stated the campaign will last from April until July.
