Is it just coincident or both crypto has some relation internally or manipulating price together?

Both currencies are following the same direction each and every time and even magnitude of % change of price is almost same. While i was analysis at some point it look like i am just working on one chart because another chart was exact same in respect of shape, impact and change.

Currently i am bullish on DBG and after analysis, i think now i am bullish on DGB and DNT both.
