So considering this I still should go long ?

Considering the factors contributing to the recent decline in GPUS's stock price, it may be prudent to exercise caution and potentially wait for a clearer picture before deciding to go long. Here are some considerations:

1. **Regulatory Risks**: The cryptocurrency and blockchain industry is heavily regulated, and any new regulations or crackdowns can significantly impact the sector and associated stocks. The recent developments in China and potential U.S. regulations could lead to increased volatility and uncertainty.
2. **Exchange Launch Overhang**: The excitement around the new decentralized cryptocurrency exchange launch might have been priced in, and the subsequent decline could be a correction as the market digests the long-term viability and competitive landscape of the exchange.
3. **Bitcoin Mining Challenges**: The Bitcoin mining industry is competitive and subject to market fluctuations. Any perceived challenges or operational hiccups in Hyperscale Data's mining operations could affect the company's profitability and, consequently, its stock price.

Given these points, it might be wise to:

1. **Monitor for Clarifying Signals**: Wait for more clarity on the regulatory front and for the market to digest the implications of the exchange launch and Bitcoin mining challenges. Look for signs of stabilization or improvement in the company's fundamentals before adding a long position.
2. **Consider a More Defensive Approach**: If you're inclined towards a long position, consider a more defensive approach, such as reducing the position size or setting a tighter stop-loss, to mitigate potential downside risks.

In conclusion, while there's potential for a rebound or long-term growth, the current uncertainty and potential risks suggest a cautious approach might be more prudent. It's important to align your decision with your risk tolerance and investment goals.
