The reason why BTC pump, is simply that new funds especially hedge funds are flowing into crypto currencies.
Be remember, the money flow should be as this:
The funds' new money will NOT go into altcoins if BTC REMAINS pumping, once BTC is steady, then it's chance for altcoins, please please remember this sequence.
What the most important is, hedge funds long BTC and SHORT ETH to hedge their risks, that's the main reason why ETH is dumping. If ETH is dumping, we should NOT invest in EC2 tokens, the correct time to invest into EC2 tokens is after ETH pumped.
Please remember this sequence, and hope you earn a lot.
