Poloniex is my only trading platform.at present all the altcoins in polo are experiencing a huge correction and probably are trading at their 52 week low due to the bitcoin rally.is it the correct time to double the investment to maximize the returns ?what is the best portfolio for 4btc investment?
Best would not be the appropriate term but rather something interesting to try. Those other alts can't be tagged as the best since their price is a matter of pumps and dumps. And doubling the investment doesn't have the right time but rather right tyming and ability to take a ride when there is a pumping scene.
Since Polo only listing coins that has active volumes, I suggest choosing those alts that has established a daily active volume.
