I guess those searches happen when Bitcoin drops recently.
Since many think about that maybe Bitcoin dominance has decrease and many people now maybe focusing to buy alts rather than staying on Bitcoin.
But let see if there's a sudden changes will happen in market since if ETH would able to break its past ETH and continue to have a good pump then maybe we could see the alt season will happen. For now we are not sure and everything we have seen is just another speculation so lets monitor the market to see the next possible situation will happen.
