I panic dumped right at the bottom, then had to buy back after it became clear it was all bull. I'd never have panic dumped if it wasn't for all the Satoshi lies.
By "panic dumped," you mean sold for (at most) $12 lower than current spot? Well, you know what they say about weak hands...
Actually, any of us are capable of making various mistakes in how we treat our bitcoin holdings, and I have been guilty of some of these mistakes myself, wether you label it greed or portfolio protection - yet if you believe that you have pretty solid information that there is going to be a price movement of a few percentage points, it may be good to buy or sell accordingly with a percentage of your holdings.
I've done it a few times, and made mistakes, and in those instances, I had to lay off buying or selling for a while in order to recover.
Specifically, I recall that in about mid November 2015, I was buying (on the way down) and selling (on the way up) in about $5 price increments, and for some reason, I had engaged in some conduct, which I recall was that I had sold way more BTC than I should have at $315, and I said to myself, "shit, that's a screw up, and in order to make up for that screw up, I just have to refrain from either buying or selling until the price comes to my points." Thereafter I did not permit myself either to buy or sell until either below $300 or above $329. I did not know which price was going to occur first, and after I resolved to make that plan as a means to recover my portfolio, I did not really care which direction occurred first. In that particular scenario, I recall that BTC prices fell below $300, I made my purchase, and thereafter I was able to resume my previous buy/sell techniques (with a bit of a lesson).
