When you say most of the market, that simply means that there is already an altcoin included on it because the market is composed mostly of altcoins if not tokens and there is only one bitcoin. You need to be specific and say the name of that altcoin that have been left behind in the recent boom because most of the top altcoins are performing better now together with their master bitcoin.

When btc is rising, we can expect that altcoins will do the same thing but they can't cross over bitcoin. It should be btc that must first take the lead before them. They need to give way to the king. In terms of a new altcoin, a new altcoin can always boom but that can be for short term only.
