Now not withstanding I proper believe whales play the market around xmas every year to try to increase their own bag sizes (check market cap graphs across last could of years). This is further evidenced imho because when btc really takes a hit so does every single alt (or people with money would just move all alt money into btc at the time). Last point being the majority of the swing/retracement happens in 12 hrs . Long enough to squeeze newbies to sell investments at a discount, quick enough that people like me can't get new money cleared into crypto in time to buy (suspiciously enough all instant purchase avenues were down for me at the time).
Anyway all whale/insider trader conspiracy stuff aside main point of this post is to check your weekly graphs occasionally, not just your daily and hourly.
Also I think XRP is just about to get it's weekly cross (like the positive one).
