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.
Last year, a California man pleaded guilty to a mining fraud of at least US$722 million through the BitClub Network. In February, a New York man pleaded guilty to running a Ponzi-like hedge crypto fund that stole about $90 million from more than 100 investors.

But before you look further make sure you’re aware of the risks when it comes to cryptocurrencies in general.
Bitcoin’s (BTC) price hit another all-time high at $69,000, while Ether (ETH) continued its long slog toward $5,000 after reaching a new high at $4,868 earlier on Wednesday. Shortly after hitting this fresh milestone, however, traders began taking profit, leading to a nearly $7,000 drop, which plunged BTC’s price below $63,000.
