It can be observed that in the short term (2–4 and 4–8 day period band) there is no consistency in results; in some cases the null hypothesis can be rejected and in some cases it cannot. In the medium term there is more consistency in rejection of the null hypothesis in favour of bubble regime coherence values significantly exceeding the non-bubble regime values. In the long term, the proportion of instances exhibiting statistical significance reduces, with the majority of cases in the 256–512 band not being a rejection of the null hypothesis. This reduction of statistically significant differences when considering longer term periods further emphasises the point that it is the medium term in which coherences tend to strengthen during bubble regimes.
Bitcoin–and the cryptocurrency industry as a whole–plunged this year, after a gravity-defying surge in recent years. The price of the digital coin hit nearly $20,000 late last year. And then in early 2018, it began to fall. Though it hit a few plateaus, the price has still tumbled; today it hovers at a little over $3,000.

“We’ve seen a tremendous amount of inflow of attention, and that’s going to continue to drive the growth of the industry for a while now,” says Abner.
However, cryptocurrency is unique as it is typically decentralised so there is no control from government interference. Cryptocurrency uses something called a blockchain.
