Newbie question: I’m guessing forks are like stock splits?  But it doesn’t seem to affect the price of the original pre-forked BTC.  I’m wondering if we will see more forks down the road.  Do we know of any upcoming forks? 

There are many guides on youtube on what exactly a fork is. I'd recommend to check those out. No one will describe it as detailed as done there.

The first and foremost piece of information all bitcoin holders should know is that in the event of a hard fork that splits the blockchain, bitcoins you possess will be perfectly safe.

Over the past year or so hard forks have gotten a bad reputation for political reasons, but in actuality, most types of forks are merely protocol upgrades. A blockchain split occurs during a hard fork which in turn branches the chain into two parts. If this happens, there is nothing a bitcoin holder has to do but wait and watch the fork unfold.

The folks at the subreddit r/btc have compiled a very well written frequently asked questions post concerning protocol upgrades and how users are affected. The thread gives details about the hard fork process and what to expect.

It's hard to know how many Bitcoin forks just happened, because there are only few news and people appears to have no interest at all and only few are talking about those forks, but if you search the web you will find some sites that have the list of forks that just happened and also those upcoming. And even those are free money there are no exchanges that wants to list them, so how can we take that money out if there's no support from exchanges? and there's even no official wallet for those coins. I managed to claim some of that fork coins BTG, SBTC, BCD but I don't know if there are exchangers for those coins, only found exchangers for BTG.
