You can make profits from fork if you've invested in alternate coins, buy them now since price is low and check your holdings once the fork is done. Just make sure that the coins you are investing are moving and not those dead coins.
Be careful with alts, there are a lot of useless ones out there. Also note that there's no guarantuee that whatever particular alts you choose are going to fully recover. Some very well may just fall out of favor and will not get back up, in which case you'll have to decide whether you cut your losses or try to come out on top a couple of months / years further down the road.
