If that is about the price, Bitcoin is not at highs because the price will increase more. But if that is about getting list on Wall Street books, that also not in highs because Bitcoin will get in highs when Bitcoin become additional payment systems besides of using fiat.
While bitcoin prices will continue to rise further in the future as adoption spreads globally, but bitcoin prices are no longer low. It has grown from under $1 to $100k and is now worth over $2 trillion, which is not a small number and not low either.
I also suspect that bitcoin could become both part of a national reserve (safe haven) and a complementary payment system alongside fiat money. It can only be 1 of 2, and I choose bitcoin to be used more by the world as an asset.
When it comes to payment systems, the factors people care about are speed and transaction fees, not decentralization. So if crypto is the world's choice as a payment method, stablecoins or altcoins will be the choice, not bitcoin, IMO.
