Damn, that is not a nice feeling...at all. I made some similar mistakes recently. The market has been a mess ever since the China ICO ban, the BTC forks and the epic bull run. It is easy to make the wrong moves at times like these and trade with emotion. I had to keep dumping and rebuying my ETH as the price went up and down with BTC but did not buy back in quick enough. Of course, ETH went and mooned lol, I was priced out. I did not have all my usual XVG stash either, just to rub salt in the wound. Win some, lose some. Good that the alt market is starting to recover now though, ready for 2018.
