How can we prove that Bitcoin purchased through a Spot ETF, thus resulting in the creation of a "trust unit", reflects the purchase of real Bitcoin?
The category of investors who may apply to ETFs is the category of investors who are more interested in speculation than value, meaning that they do not want to buy Bitcoin or invest in it, but rather they are looking for value in trading without risking buying Bitcoin, learning how to generate the private key safely, and selling it in the future, so there will be a number Less people buying Bitcoin and more money for the big whales.
The disadvantage of ETFs is that it is easy for whales to empty the price pumps so that we will not see a crazy increase like we did in 2017.
