Wallstreet investment in cryptocurrency so far, and announced, looks to be a net negative. Most of what the involved parties promise to do is buying/selling papers, not actual coins (making the banks rich, not cryptocurrency holders). In effect their involvement creates real, and strong inflation for Bitcoin, Ether, XRP, and other exposed assets. Not only that, but people that may actually have bought real coins are now buying the papers instead. As a result, Wall Street is taking buyers out of crypto and stealing market share.
