Though this event is over, everyone must remember the slogan "Not your keys, not your bitcoin."
Unfortunately, rookies don't care, nor do mostly know what a private key is. Maybe that things will play out in a more favorable way next year, but then again, the effect will still be negligible.
We learn by falling, and this definitely applies to most of the rookies here. Let them burn themselves and based on that horrible experience build up a dislike towards anything with a centralized nature.
Coinbase has over 800k BTC in its reserves, and Xapo has an amount quite similar to that. The worst part is that Xapo secures coins for OGs as well. If they don't take self storage seriously, why would noobs do?
