CoinShares, a UK based digital asset investment firm is asking investors to help them fight against the ban on the crypto exchange-traded notes (ETN) to be imposed by the UK’s Financial Conduct Authority (FCA). They have shared letters to investors, where the company is seeking customers to submit their response to the FCA over the proposed ban through emails and text messages, saying “The more responses the FCA receives in protest to these measures, the more likely they are to see sense and abandon these proposals.”
