Newbie here and I want to start trading soon. Just want to get tips on when to invest on btc and eth. thanks in advance! 
Welcome to Bitcoin/Cryptocurrency world buddy. If you do really like to make some trades between these coins then as a begginer or complete newbie you should know first important fundamentals to consider first before tending to jump in into trading because its not really easy on making money, you should really be knowledgeable to make profitable trades.Talking on when to invest on btc and eth is when the price is on its dip or lowest because once price do goes up you can make profits on it when you decide to sell.Thanks buddy! What exchanges can you suggest to me? I plan to invest on 2 or 3 exchanges. Is Poloniex and Bittrex really the good choices?
hey!!
there're a lot of rumors concerning poloniex and their support desk so bitrex might be a better choice. also you need to study exchange's terms&conditions in view of sec and your goverment regulations. as to investment you must decide whether it'd be on a long-term or not. if you're a long term investor don't keep currencies on exchange it's rather risky to loose. BTC is the opportunity instead of ETH which is not a payment currency and morelikely ethereum fuel. take care
