When you posted this ?Yeah XRP is really increasing but after 3 days? after US Sec File the formal case ? looks like the Holder got panicked and dump their coin right away.

In a matter of 6 hours the value dived more than 20% and not look ,more than 40% decrease in 7 days graph.

Though i have seen same scenario when Litecoin was sold ,and look at it now competitively increasing Yet we cannot Blame investors because of they wanted to Keep safe,and this is the difference of Bitcoin to other coins, the assurance of recovering from the dump.
