I usually trade on poloniex and today saw a huge downward movement in all coins dropping nearly 40%of my investment?.is it due to zcash entry?what price will zcash land at ?at present it is trading at 8btc a coin iam so surprised confused about what to do?any expert advice?
It can be due to the Zcash and altcoins usually will loose its price when bitcoin gets stronger. I would encourage you to hold bitcoin. If you are an investors in altcoins, then hold them. If you are a trader, then sell and keep your bitcoins. Don't touch Zcash. Buying Zcash now would be like trying to catch a falling knife.
