The current resistance is at $4300 and if it drops then I think that the $4100 is a good support line for Bitcoin. Although I dont think that the price will drop any time soon knowing that the hard fork is near and so the chance for bitcoin to increase in price are quiet good. When the last hard fork happened the prices were increased before the fork and then later it increased further more. So it might happen this time too and the chances for bitcoin to cross $5000 are too high.
It often said that there are nights over morning and mornings over nights. Whatever case you are in, there will be a good time coming along. You just have to be careful and putting all your efforts into it. Nothing will make your hard try useless. Bitcoins are increasing and like you said there may be another fork just ready to come.
