Which one of you is dumping Shib and not letting me get my pump on?
Not me buddy. But there is one narrative and concern that shortly after BTC is approved, the SEC and others will finally crack down hard on alts and exchanges who deal in them. Certainly the SEC can say "you have been warned" and they have warned so many times. Post BTC's corporate legitimization, all the powers that be will be massively incentivized to further emphasize the distinction between Bitcoin and "crypto". We will see this at a regulatory level, at an advertising and market education from all the ETF's, and we might just see the exchanges be pulled into voluntary compliance. Remember, many of those in traditional finance do not benefit from crypto. They are about to get BTC as their toy, and so are inherently incented to ensure BTC succeeds, and further to attract any funds in alts into the realm.
Market will also be looking closely at any language around this topic from Gensler (it may be direct, or it maybe subtle requiring a little deduction). Also interesting on ETH, which may just escape the wrath of the SEC, or may not, so we could well see Eth move in 2 totally different directions, depending on the stance taken.
