ETF's are not the answer to all of the bear problems that persist in the bitcoin market. They will certainly help, and they add some hype to it, but I wouldn't bet the house on it.
There are many ETF's scheduled but nobody knows which one will be approved. Probably not this one, but maybe the next one. There's absolutely no certainty about these things so don't spend too much energy on researching them. Better off learning about trading or technical analysis.
