Will they undermine it?
Do they fear it because they can't control it?
Will they co-opt it, package it, and sell it to the masses?
What do you think?
I don't think they fear crypto currency. I'm seeing that some Wall Street Managers have customers who have dealing into bitcoin. Those whalers you want to remain anonymous are using Managers as front for them to buy huge amount of bitcoins. And crypto market is purely speculative and I think that will work in favors of greedy Wall Street players. Money is Money for them, whether stocks or crypto's. So for me they don't fear it, but rather will take advantage of its speculative market to profit huge sums of money for their client or for themselves.
