There has been some movement on Wall Street around it: earlier this year, the New York Stock Exchange launched a Bitcoin index, NYXBT; the Bitcoin Investment Trust (GBTC), a trust whose shares can be held in IRA, Roth IRA and other brokerage and investment accounts as well as passed on to beneficiaries
Very interesting news. I have not heard it so far. So it can be a preface for more serious movements around bitcoin.
