Depends. There were dozens of opportunities for me to sell the past 2 years. But only twice has my old/prior day-trading habits urged me to try my hand (and, I didn't sell everything... this time!). Judge me if ya want. I'm well aware of all the benefits of holding indefinitely. Once BTC is out of the picture, I'll be holding as I've always done (only selling tiny amounts here and there / rarely, from peer/other pressures IRL). Again, I'm super surprised it pretty much backfired; I mean, look at it, MAID's the only major player in green.
edit: also, because of said pressures, I've gradually had to sell a bunch. Originally had 270,000 over a year ago, now I'm somewhat under 200,000 - so I saw it as a final opportunity to maybe get some of it back. (That's one of the sadder aspects, actually, of SAFE taking as long as it has: so many coins used for real life expenses.) But, I still don't feel too bad. Just waiting for that billion dollar market cap, and beyond.
