I guess it is no news anymore that whenever bitcoin is surging, all money goes into bitcoin which in turn make altcoins to dump so easily. It is always advisable that any time bitcoin is pumping, we should avoid getting into alts except you are ready to hold for long.
In the past when ever there was a big rally in
BTCitcoin the entire alt market would see a major correction only because majority of the users would sell their coins to ride the rally but this time there is a difference because ETH is expected to rally and touch its all time high valuation because of their upgrade and till now we have witnessed that the alt market was rallying along with
BTCitcoin.
