A cryptocurrency analyst has warned that selling Bitcoin (BTC) at around $74,000 would be a disastrous mistake.  He believes that fundamental factors such as the injection of liquidity by the Central Bank of China, the weakening of the US dollar index and the increasing interest of financial institutions in Bitcoin can cause a further increase in the price.  Technically, Bitcoin is in a bullish pattern and breaking the $65,000-$66,000 resistance could push the price to higher levels.  Also, BlackRock's approval to trade bitcoin exchange-traded fund options (ETF) and the interest of banks like BNY Mellon to hold bitcoin are positive signs for the future of this digital currency's price.
