SunPerp’s Buyback Commitment
The rally followed a major announcement from SunPerp, a decentralized exchange (DEX) for perpetual contracts on the TRON blockchain. The platform confirmed it will allocate 100% of its protocol revenue toward buying back SUN tokens.

The buyback strategy is designed to consistently reduce circulating supply while creating steady demand, a mechanism that could enhance long-term token value.
SunPerp’s move follows other projects within the TRON ecosystem, including SunPump, which has implemented similar token-burning programs. Justin Sun, TRON’s founder, has long advocated for such initiatives.
Perp Dex on TRON has a bright future. Tron is a major USDT network, and perps were one of USDT’s earliest use cases. It came late, but as the saying goes: the best time to plant a tree was ten years ago — the second best is now. https://t.co/FrvjQXSUCy is finally here.

A History of Burns and Buybacks
SUN has consistently benefited from token burn moves. Between August 7 and September 4, 2025, the team burned 1.65 million SUN tokens, extending a program that has destroyed 639.6 million SUN (3.2% of total supply) since 2021.
These burns have been funded by revenue from TRON’s leading DEX SunSwap and its meme token launchpad SunPump.
SUN Price Analysis: Is the Rally Sustainable?
The daily SUN chart reveals a dramatic breakout, with price surging to $0.03616. Bollinger Bands indicate the price has shot well beyond the upper band, suggesting the rally may be overheated in the short term.
The Relative Strength Index stands at 84.55, firmly in overbought territory, which often signals the risk of a pullback or consolidation. At the same time, the MACD has turned sharply bullish.

In the bullish scenario, SUN could break through the $0.038 to $0.040 resistance area, paving the way toward the $0.050 level as the next major milestone.
If momentum and buyback activity continue to accelerate, the psychological $0.10 level could come into play over the coming months, making SUN the next crypto to explode in 2025.
On the other hand, a correction could drive prices back toward $0.030, with deeper retracement possibly testing the $0.025 support zone if profit-taking intensifies.
