When the spectre of restrictive regulation hovers over the cryptocurrency markets, steep drops invariably occur. If it happens to concern China or the US, brace yourself if you’re an investor—the market never stops trading, and what took months to build can crumble to nothing in an afternoon.
Altcoins can also be used to create smart contracts. These smart contracts can be automatically executed based upon certain conditions. There is no need for third-party involvement and so they can be done immediately. Smart contracts can be used in transactions as diverse as property, stock, and gas, making them a very interesting investment.

Wavelet coherence plots as above highlight areas in the time-frequency space where the two series co-move. The warmer the colour, the higher the coherence (which can be interpreted as correlation) at that location in the time-frequency space; the colours used in this work range from dark blue (0, no coherence) to yellow (1, strong coherence). Statistically significant areas of coherence are surrounded by a thick black line.
For the sake of clarity an explicit definition of short, medium, and long term is required. In this work short term refers to the 2–4 and 4–8 day period bands. Medium term refers to the 8–16 and 16–32 day bands. Long term will be used to refer to the 32–64, 64–128, 128–256 and 256–512 day bands. The short, medium, and long term bands will be considered separately to begin with, and then considered collectively alongside the results of the GSADF bubble test.
