Only 12.9% of BTC supply remains on exchanges
Since August, when BTC’s price started gaining upward momentum, the percentage of coins on exchanges started dropping. Currently, just 12.9% of Bitcoin’s circulating supply ($163 billion) is sitting on cryptocurrency exchanges.
When investors keep their coins on trading platforms it is often a sign that they are preparing to sell their BTC or other crypto. Moving BTC off of these platforms usually means they’re ready to hold onto their coins for longer periods. This reduces available supply and is viewed as bullish for the price.
