Bitcoin is the basis, the standard here. Looking at something not from the Bitcoin point of view is a wrong thing. One can use USDT to measure them though.
It does not mean that we are all bitcoin lovers and altcoin haters. Altcoins never make any impact on the market in the long run. It is bitcoin which stands tall.
however, Bitcoin's dominance in the crypto market is still very strong. all of them may still exist and will continue to depend on the capabilities of Bitcoin for a long time.
