In the early days of Netflix, the top executives went to Blockbuster to offer to sell Netflix for a price that was a small fraction of Blockbuster's market cap. The Netflix executives also said they wanted to be in charge of running the streaming business within Blockbuster. The Blockbuster executives practically laughed the Netflix executives out of the room so the two sides went their separate ways.
The rest is history.
I'm also reminded of when Amazon was a young company and Barnes and Noble announced it was getting into the online business. An analyst said that Amazon.com was now "Amazon.toast".
Again, the rest is history.
I would be very skeptical of banks trashing bitcoin and other crypto assets. Blockchain technology is going to radically transform the banking business. Bankers who don't recognize that are whistling past the graveyard.
