It's a competitor and a potential threat in case you as bank completely ignore it. If you as bank or whatever corporation utilize Bitcoin in various manners, you will benefit as well from the massive future potential Bitcoin and basically crypto entirely has to offer. Instead of looking at Bitcoin as being a threat, one should look at how Bitcoin can lift your entire operation, and the global economy as well in the long run. Banks may not see what we see in crypto, but this will soon be a multi trillion dollar asset class, which if whatever entity in this market utilizes its opportinities to the fullest, will greatly benefit from this development as well. At this point in time it's an unjustified level of fear that holds them back, but I'm fairly sure that this will change in the forthcoming years.
