We have been in the last period to see Ethereum and altcoins stay at their bottom in BTC pairs. If you hesitate too much and don't step in altcoins, includes Ethereum in coming days or weeks, you will deeply regret for you hesitation. Such perfect opportunity to grap very cheap altcoins before the bull run (after year-long bear market) does not happen too often. It is just happen some years per time, so it is time for investors whom still hesitated to sit down and seriously think of investment.
