Although the crypto market has seen a significant rebound yesterday, with most especially ethereum surging more than 12 percent, the entire market has touched its annual low this week. Bitcoin has shed more than 60 percent of its value but that means when compared to most other coins, such as XRP which falls more than 90 percent from the height at the turn of the year. A number of passengers in the crypto industry have recently praised bitcoin as the most reliable digital asset when issuing warnings about altcoin and initial coin (ICO) offers. Sonny Singh, a chief commercial officer at BitPay's crypto payment processor is the latest to voice his support for the camp "yes to bitcoin, no to altcoins".
