If we see a downtrend of our favorite cryptocurrencies then it is the opportunity to buy them at a discount.  We always talk about DCA and DCA is most effective when the market is in bearish mode.  With the downtrend of these altcoins and Bitcoins, it is our window of opportunity to accumulate more at a discounted price.  So I think we don't need to hesitate.  Buy while the price is at a discount, we don't know when will be the next opportunity so better to take advantage of it now.
