well there is no proof!
what you quoted is just some business trying to advertise its services by saying they are handling a lot of money from their numerous investors!!!

the fact is seen on the charts.
altcoins are getting dumped hard and that means there isn't any investor going near them anymore.
bitcoin is also staying the same price for the past 2 months which means only those who were around are accumulating while others are staying scared and watch for the rise before they start.
