Patterns in Crypto

Has anyone else been following the patterns that cryptocurrency seems to be following?
For the past month or so I have been able to follow BTC, ETH and LTC graph patterns pretty well.
Well enough that I have luckily only made purchases when the coins seem to drop to their lowest.
This may not seem like much since all three currencies have gone up and fluctuated but it is a big deal.
If you are buying low by following the pattern then you are making even just a little bit of a profit every time the coins raise up again.
Im set on the idea that if the patterns continue as they have then we will see a nice drop in ETH price this Thursday.
I have been watching this because when it is low you make more when you by and re disperse to other currencies like Ripple or Tron.
I have been doing well i hope this little bit of information can help someone out. New or seasoned in the crypto world.
Interested in hearing if anyone else is following this pattern?
