Please be carefull with just following the portfolio of bluemagic.
What I think could happen:
Bluemagic decides that coin xyz is a good coin and they buy the coin
Due to that action the coin goes up
People who follow the portfolio of bluemagic decide to do the same: depending on how fast you follow you buy in on the coins while the price goes up more and more
Result: you buy in on the coin while the price is rising or high
Bluemagic sees the price going up and decides to sell the coin for profit
Due to that action the coin goes down
People who follow the portfolio of bluemagic decide to do the same: depending on how fast you follow you sell the coins while the price goes down
Result: you sell the coin while the price is going down or low
Need I say more?
Correct, that could apply to a low marketcap coins, specially those ones of extreme fund and much probably Extreme funds will not be public information in the future because of this factor (possibility to do a P&D scheme)
But for all the other ones, you should need a really big bunch of $$ to make this process happen (10-20M at least). Let's be sincere, not so many people is looking at Blue Magic right now.

Even with that, this is not the same as wall st. behaviour? I think we all know where are the best investors and companies positioned in and what happens when they move on... It's just called market power or market influence and you cannot control that
