Could altcoins attract funds that exit Bitcoin? Let\u2019s study the charts of the top-5 cryptocurrencies that may extend their up-move in the next few days.BTC\/USDTBitcoin turned down from the resistance line of the rising wedge pattern on Aug. 14. This suggests that the bears have not given up and are defending the resistance line aggressively.BTC\/USDT daily chart. Source: TradingViewThe BTC\/USDT pair could now drop to the support line of the wedge, which could attract buyers. If the price rebounds off this level, the bulls will again try to resume the up-move. A breakout and close above the wedge will invalidate the bearish pattern and open the doors for a rally to $53,000 and then $60,000.The upsloping moving averages and the relative strength index (RSI) in the positive zone suggest that bulls are in control.Contrary to this assumption, if bears sink the price below the wedge, the pair could drop to the 20-day exponential moving average ($42,682). If the price rebounds off this level, the bulls will make one more attempt to resume the up-move. But if the price slips below the 20-day EMA, the pair may drop to the 50-day simple moving average ($37,176).BTC\/USDT 4-hour chart. Source: TradingViewThe bears are posing a stiff challenge in the zone between $46,743.47 and $48,144. They have pulled the price down to the 50-SMA on the 4-hour chart. If the price breaks below this support, the pair could drop to $43,770 and later to $42,451.67.The flattening 20-EMA and the RSI near the midpoint suggest that the bullish momentum may be weakening. If the price rebounds off the current level and rises above the overhead resistance zone, it will indicate that bulls are buying on every minor dip. That will suggest the resumption of the up-move.ETC\/USDTEthereum Classic (ETC) broke and closed above the overhead resistance at $63.56 on Aug. 13, completing an ascending triangle pattern. This bullish setup has a pattern target at $94.91.ETC\/USDT daily chart. Source: TradingViewUsually, after breaking out of a pattern, the price turns down and retests the breakout level. In this case, the ETC\/USDT pair could retest the $63.56 level in the next few days. If bulls flip this level into support, the pair could start a new uptrend.The rising 20-day EMA ($57) and the RSI in the overbought zone suggest that bulls have the upper hand. If the price breaks below $63.56, the pair could drop to the 20-day EMA.A strong rebound off the 20-day EMA will suggest that the bullish sentiment remains intact. The buyers will then make one more attempt to resume the up-move. This positive view will be negated if bears pull the price below the 20-day EMA. That could result in a decline to the 50-day SMA ($51).ETC\/USDT 4-hour chart. Source: TradingViewThe 4-hour chart shows that the pair is in an uptrend.
