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.
The answer is very simple: such a big growth can have those altcoins that have low market cap and at one moment demand is much higher than supply. Talking about bitcoin, it already has a big number of holders and it doesn't have such sharp jumps in demand over supply. Moreover, when bitcoin grows too high, many traders open a short position which also puts pressure on the price.
