My opinion: this could happen. If it does, consider that it's about two or three days quicker to move money into a broker account than into a coin exchange. Whrn I deposit a check to my checking, I can move that money to etrade as soon as the bank clears the check.. and etrade let's me buy against the transfer as soon as I order it. If I transfer that money into Coinbase instead of etrade, Coinbase makes me wait 5 days to buy Bitcoin with that cash. So, assuming these "wallstreeters" get benefit checks as direct deposits on 1/15, I'll be looking for a spike in crypto stocks first, followed by a cryptocoin bump a few days later. The coin bump should power a second bump in crypto stock prices. At least, that's the advice I got from my Talking Elmo doll...
My point is, don't interpret this article to mean that Bitcoin will definitely explode on 1/15, don't despair if there's a few days lag.. it's not going to be a single Tsunami wave at 50 feet high, more like "Surf's up!" for a week or so.
