Bitcoin (BTC) price continues to limp lower as traders in the U.S. hit the BBQ to enjoy the upcoming Memorial Day holiday on May 31 and regulated futures and options markets like the CME are closed through the weekend.Data from Cointelegraph Markets Pro and TradingView shows that after a brief attempt by Bitcoin (BTC) bulls to rally above $37,000 in the early morning hours on May 29, the price has tumbled below $34,000 as the support needed for a move higher failed to manifest.

Source: DecentraderThe analyst went on to further state that if Bitcoin is able to find solid support in the low $30,000s, the 20 WMA could turn into a major resistance zone in any attempt to move higher. Filbfilb said:“A drop lower would likely make the low $20,000s or the 78.6% retracement a likely target. As such, price action over the next week is particularly important.”At this point, according to filbfilb, it is crucial for BTC to reclaim $37,500 “to avoid a retest of weekly support.” Should Bitcoin manage to stage a rally and break above $40,000, filbfilb identified the previous support/resistance zone at $45,500 to $46,500 as the next area of resistance that will need to be overcome. Ether draws the line at $2,300Ether performed slightly better than BTC after it sold off back to the 61.8% retracement as the price was able to bounce back above the 20 WMA, but was ultimately rejected at the “critical pivot price” of $3,000 as the recovery momentum faded.
