Price memory is not a term I've heard before but it makes sense hearing you explain it.

I've been acting in this way with my Steem - I was going to cash out some steem into USD, but I'm waiting until it goes above $2 per steem again. If it had never been above $2 before, I might be happy to sell at $1.50. But with my memory of $2.30+ steems, I can't bare to sell below two bucks!!
