Will Coinbase, Binance, and the others survive?

Will Coinbase, Binance, and the others survive... that is the question, and here's my humble opinion:

I believe the powers that be will continue to destroy (already happening) the existing players, think Bittrex. And the JP Morgan's, Morgan Stanley's, Goldman Sachs's, Fidelity's, and Robinhood's of the world will just start doing what Coinbase and the others were doing once they are gone.

They will setup cryptocurrency custody and trading platforms once they successfully squash everyone else in the space, and their buddies over at the Securities and Exchange Commission will create rules that only benefit the old guard, rules that will keep everyone else from getting in the space to compete with them.

What is your opinion on this matter, and thanks for taking the time to read my post, and for possibly leaving a comment to add to the discussion.
