The global crypto market tanked to $1.45 trillion after reaching an intra-day high of $1.59 trillion early morning today. This trend-reversal was initiated after an official statement by Amazon squashed the speculation that the company plans to adopt Bitcoin and crypto payments. On the 24-hour period ending 9 am IST, the overall market cap has declined by 4.4 per cent though trade volumes increased 26 per cent on the back of momentum gained yesterday.
