Tether (USDT), the largest stablecoin in the world, has just crossed a historic threshold of 120 billion dollars in market capitalization. This news, far from trivial, comes in the context of "Uptober," a traditionally favorable period for price increases of Bitcoin and other cryptos. While the crypto market is often unpredictable, the massive increase in the supply of stablecoins is often seen as a key indicator of growing investor appetite. As we stand on the brink of a new bullish wave, this signal suggests significant movements in the weeks to come.
