Who are the buyers of coins?

Money laundering also need to buy bitcoins

Buyers:

Every day bitcoin lives, I get more confident in the system.
I just buy. I feel happy when I receive them.
I usually don't look at the price too much, I just buy the relative dips. I'm not really good in catching the knife.

was using email in 1991, it was pretty widespread in universities at that time.

Have been using e-mail since 1986... Knew in the mid-to-late 80's that packet-switched networks (i.e. TCP/IP) are the future and not circuit-switched ones (X.25), and that even phone calls would be routed over IP networks. Sadly, I did not bet my meager student wealth on it then :-(
Now, with wife and family, I can't just bet my meager employee wealth on bitcoin, even though I'm equally convinced that it (or at least the blockchain concept for currency transactions) is the future. So I just gather small amounts. Still I'm happy to know that at most 0.1% of the world population can ever have more bitcoin than I have now
