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.
Seriously I see no reason why you should be so bothered about this rise in altcoin with the rate at which we saw bitcoin rise last year till this year, the rate is quite alarming and pleasing to see it rise to that level. Or maybe you are late to the club the rate at which you see those coin rise will be the same rate you will see it dropped and you will be amazed.
