No I don't think so, though there might be a little influence on the general market to fluctuate, but that's not what it's all about, because they are not the only whales controlling the market, we have a large number of them, the more others are selling, some are buying it and that is how the circle continues in both demands and supply, what we are going to also consider on this note is that, we may also have to realize the number of holders who are not whales and are also making a significant impact on the market, these are people making daily transactions in buying and selling everyday, causing the shift in its demand and supply, thereby impacting on the market price to fall or rise, ETF is just by the way a booster to Bitcoin utility.
