What alt pump do you think it was that caused this?
there are none to be honest, don't know what is the source of the OP, because last i checked altcoin scene is even more dead than bitcoin
I seems to me that every time a hardcore pump happens with an alt coin, lately also known as crave, which was the last great event, the price of Bitcoin drops. I see this as newcomers taking advantage of the crypo market, that bought into a pump group and took their profit asap. I do not feel that any crypto savvy folks would just sell their profits at the current price. I guess i could write it off as shit happens, but taking advantage of a unstable market and making it more unstable just equals total disaster.
it's not always true, because dumping btc for fiat and buy altcoin, is much slower and less anon, than buying bitcoin and then using it for pumping altcoin, so no, pumping alcoin should increase btc price, like it happened with auroracoin
