Grayscale Investments amended its S-1 filing to convert the Sui Trust into a spot ETF on Tuesday, February 17, now called GSUI. 

This move brings SUI closer to mainstream financial markets, offering institutional investors a seamless way to gain exposure to the token. The transition signifies a key milestone for the cryptocurrency’s adoption on Wall Street.

Coinbase will serve as the prime broker and custodian for the GSUI ETF, providing essential infrastructure and security. 

The partnership strengthens Grayscale’s efforts to make the token accessible to institutional investors while ensuring regulatory compliance. 

This collaboration also highlights Coinbase’s growing role in facilitating institutional crypto investments, enhancing trust and legitimacy in the crypto space.

SUI Price Struggles Below Key Moving Averages

Despite this landmark, the token’s price eases off the rally with price action ranging in the mid Bollinger Band at 0.985, according to TradingView. The 20 and 50 EMAs are flat and intertwined with the price candles, indicating a balance.

 Price rejections at 1.04 and support above 0.93 indicate a calming of price volatility after a period of expansion. The momentum indicator shows a balance as buyers and sellers halt their pace.

From a structural perspective, the token formed a new higher low but was not able to nail down that new higher high. Resistance clusters range from 0.99 to 1.02, while support ranges from 0.95 to 0.96. 

Staying above the EMA clusters could set up the token to test the upper band once again, while dipping below support could set up the token to potentially test the lower band. Overall, the bias is mildly bullish and ranges within a defined range.

Momentum Indicators Show Weak Bullish Potential

Currently, the RSI stands at 46.52, floating closely to the 50 level. The level seems to be a tug of war between buying and selling. 

However, a level below 50 may indicate a slight bearish bias. In addition, the RSI level is below the 14-period moving average (the yellow line), showing a mere hint of weakness in the existing trend.

MACD presents a softer view. The MACD line is positioned slightly above the signal line, reflecting a nascent positive bias, but the gap is narrow. 

The histogram, which measures the gap between the lines, is also in a minor positive territory, supporting the faint positive view. Still, the MACD is in negative territory below the zero line, reflecting a bearish bias in the long term.
