We are all on "borrowed time" pretty much when it comes to mining. Our only catch at success is to sell ZEC, buy BTC and keep it and hope SEC approves the ETF and bitcoin goes to $10,000/coin.
You say that because you want to grab all the coins at a lower price because near this month zec price will go very high!
Maybe ETH or ETC, but not ZEC.
ZEC will not go very high because every month there is a large percentage of supply entering the market.
The price is at all time lows...but the market cap is at all time highs. All because of the daily supply of 7,200 ZEC coins.
