As legal initiatives begin taking hold such as psd2, or the U.S.'s cryptocurrency act, this trend is likely to continue. 

When she says stablecoin project, I think she doesn't mean usdt, but one that has existing legal contracts with companies, such as $link, or $bat; though it's equally possible "stablecoins" will gain further legitimacy.
