i don't this so. if the ETF can have any kind of effect on bitcoin, that would be a temporary one where it gets hyped up a lot and then price has a sudden rise kind of thing and in then end we are left with a small bubble and coming back from it.
Whether that ETF will happen or not. For me it is going to be the best thing to wait. There are more upcoming great years for bitcoin and just sell it when you really need to do so but if you don't then just let it be and wait for the right time to sell it. I keep on believing that bitcoin will go beyond on its current price.
