Got out several years ago now - luckily (and it was at at least as much luck as skill) with a very small profit. Was mostly silly enough to think that there was a (small) long chance they would succeed back then. Was wrong.
Trade it if you think you can time trades well - but don't linger or expect long-term progress.
