Why should you care who holds Bitcoin - institutions, whales, or average people?
I was going to say this.
In other words do not give everything to the big whales and try to remain in this select club because once you do it you may not be able to take them back. You may think you can but most probably you won't.
I see many people worried about the big whales nowadays but let's not forget that they are playing an important role in the rise in price. If Bitcoin ever gets and surpassed $1M they have will played an important role. Not everything is bad about them.
I am more worried about my bitcoin plan than about them.
