The prices of almost all major cryptocurrencies are trading in the green on Wednesday, thereby uplifting crypto investors’ sentiments ahead of the US Federal Reserve announcement on interest rates. The global crypto market cap is up by 2.48 per cent at $2.01 trillion but its trading volume is down by 13.82 per cent at $88.34 billion, according to Coinmarketcap data. This low volume might be an indication that investors are reluctant to sell their holdings at the current price and are expecting the prices to move up further.
