The Bitcoin Miners Supply Held chart reflects the amount of Bitcoin held by miners. It's a crucial tool that traders can use to gauge market sentiment. A declining chart signifies miners are selling their rewards, possibly expecting a bearish market, which may lead to a drop in Bitcoin's price. Conversely, an increasing chart means miners are holding onto their Bitcoin, hinting at a bullish market sentiment and potential price increase. Use this info to position your trade accordingly: buy when the market's bullish and sell when it's bearish.
