Everyone of the bitcoin holders think the same way as you think. They wanted to hold bitcoins and sell for huge profits later. Some did buy at 1000+ bitcoins for $1. Most sold those coins when bitcoin surges heavily. Now bitcoin down by a large amount than it was in 2014. People might have lost a lot of dollars when they buy at $1000. So, it is hard to say you can take huge profits if you hold bitcoins. If you've bought it in very cheap, sell it if you feel it is highly profitable.
