Wall Street won't be that important until we see an ETF get approved - most of Wall Street is not allowed to own Bitcoin or cryptocurrencies directly. So the big thing to follow will be ETF submissions and responses from SEC. I think the declining Bitcoin market share is an opportunity - all it takes is the launch of the Lightning Network for everyone to suddenly switch from altcoins to Bitcoin. Recall that while Bitcoin had its bull run from October to December, everyone thought altcoins would never see any love ever again. Now people think Bitcoin is too slow and expensive, thus Bitcoin will die a slow death and altcoins will start to take over its market share. But I bet you that Bitcoin will come back with a ferocity, as it always does.
