We have a graph here of the largest owners of Bitcoin and the #1 largest owner is Grayscale Bitcoin Trust (GBTC).
Everybody who owns GBTC, wants to sell it. If the SEC allows for Bitcoin ETFs, GBTC will finally be able to dump their Bitcoin into the market and repurchase GBTC shares to balance out its discount. There is very little demand for an iShares Bitcoin ETF. If people wanted to buy a Bitcoin ETF, they can already buy the Bitcoin futures based ProShares Bitcoin Strategy ETF (BITO), but it only has $883 million in assets under management. The fact that so many people recklessly buy Bitcoin and other Cryptocurrencies due to speculation over ETFs, which completely defeat the purpose of decentralized digital currencies, proves that Crypto remains a massive bubble that has so much further to decline.
Gold is the only major asset that is about to hit new all-time highs in the upcoming months.
