Using algorithms to analyze the blockchain data, we find that purchases with Tether are timed following market downturns and result in sizable increases in Bitcoin prices. Less than 1 per cent of hours with such heavy Tether transactions are associated with 50 per cent of the meteoric rise in Bitcoin and 64 per cent of other top cryptocurrencies.
