Sure the survey results are somewhat interesting, but it doesn't really give us much info beyond what the overall investment thought-process of the Twitter population that answered is. There are no demographics information pieces to give some context to the opinions of everyone. For all we know it's a bunch of old single women that are answering. Age brackets, income, all that kind of information would have been a lot more helpful and given a lot of information as to who is actually interested in investing in Bitcoin.
This is why I think twitter polls are mostly useless aside from yes/no answers or very simple pieces of information; there's too little context to make the answers of more complex (extrapolation-wise) surveys worth looking into.
Don't get me wrong, you have the right idea, it's just hampered by Twitter's platform.
