With some coins going up 50% or even l00% in a day or few days or in a week... any reason why bitcoin doesn't do that almost ever? Look at binance coin and many of those other coins that are literally doubling in a week. Now the btc dominance is going so low. And even when btc goes up... you don't ever see it going up that much percent in a week. I mean... its rare to see bitcoin say go up 50% in a week yet tons of altcoins do it.
Look at the capitalization of Bitcoin and understand, that the greater the turnover, the harder it is to change the price of an asset. Bitcoin has a huge number of market makers. Of course, the young asset will move much stronger in percentage terms. Do not forget, that Bictoin has already done + 1500% starting from $ 3800. And this is a lot.
