I made a chart for my own reference studying the sine-wave patterns of Decred / Bitcoin . There are 3 different sine waves with different frequencies and impact which I found in the chart. The larger sine waves seem to have more impact and smaller ones less so. The sine waves do not tell us what price Decred will go to either up or down. So there is no correlation between where I put the top or bottom of these waves and the Decred price. Just that when I make the sine waves smaller, it reminds me it has a smaller impact and larger, it has a larger impact . The sine waves show shorter term, medium term and longer term historical trends and where they may go in the future. This can be helpful to me for buy and sell possible places.

The red and green backgrounds line up with the dark blue sine wave , also a reminder for visual effect.

Not a recommendation to buy or sell but I am happy to hear your thoughts/ideas. Thanks.
