I am really not concerned due to institutional investors. They are accumulating, that doesn't mean you can't buy it. Rather, it's good for a healthy growth of Bitcoin and better for retail investors. Due to heavy accumulation by the institutional investors price is going up. And it's better for us to get profits from Bitcoin investment. I am not concerned because they aren't going to sell Bitcoin very soon. Even if they want to sell, they won't do it at once.
I think rather than being concerned, we should take advantage of that. When massive adaptation happens, then it's a chance to increase your portfolio as well. We just need to take decisions at the right time about our holdings. Bitcoin is accessible for everyone; anyone can accumulate it anytime. So nothing to worry about. Just be a part of the revolution.
