Pretty sure most people didn't buy BTC at $20K, which it never actually even reached. It didn't spend much time above $19K either.

If you look at the charts, it didn't even spend much time above $16K or so.

Most people lost huge sums of money because they invested in alts which are like 90% red. Look at Ripple or Dentacoin or what-not.

I assume most invested at like $12K and its half now, so its only a 50% loss. However the alts are a different story.
