The case for Bitcoin (BTC) to continue rising to $40,000 and beyond by the end of the year has been strengthened, with centralized exchanges seeing massive Bitcoin outflows recently. Glassnode data shows that since November 17, more than 37,000 Bitcoins (valued at $1.4 billion) have been withdrawn from exchanges. Over $1 billion worth of BTC has flowed out of exchanges in the past week. This may suggest bullish sentiment.
