Its alwsys good to invest but buying price or selling price determination is the key and that's where technical analysis come in.. i am a trader and to analyse altcoins first i make technical analysis of Bitcoin and now started Ethereum as well then the coin.. i was sharing for this fall in currencies from last 3 weeks through my blog posts and i think we will see some relief.. but i don't expect anything significant on upside before 1st August.. BIP148 decision is on 1st August so that will decide next move..
