Bitcoin recently tested a crucial support level of $66,800 amid concerns over a hacking incident, but has since shown signs of recovery. However, May wasn't particularly favorable for altcoins, with most seeing minimal gains or significant drops, except for Ethereum. Looking ahead to June, market predictions vary for major cryptocurrencies.

Cardano (ADA), a leading altcoin known for its proof-of-stake (PoS) model, faced challenges despite its market cap. After peaking at $0.50 on May 21, ADA saw a notable drop to $0.44, signaling a shift in market momentum against bullish trends. The Awesome Oscillator (AO) has been bearish for 60 days, suggesting caution for ADA investors in June. Potential scenarios could see ADA testing lower support levels around $0.40 and $0.38, influenced by market sentiment and external factors such as inflation data.

Bitcoin Cash (BCH) also encountered difficulties, losing 10% of its value recently. Concerns over the movement of assets from the MTGOX exchange have added to selling pressure, impacting BCH negatively. The Chaikin Money Flow (CMF) indicator indicates ongoing capital outflows from BCH since late May, with the SAR indicator pointing to further risks of decline. Speculation persists regarding BCH's price trajectory, with attention on potential drops below $459 amid market uncertainties and news triggers like MTGOX asset distributions.

As June unfolds, the cryptocurrency market remains volatile and subject to unexpected developments. Investors are advised to stay informed and exercise caution amid fluctuating market conditions and potential sell-offs triggered by news events.
