i have read up about the bitcoins split... how many splits has it gone up to...?
I think you are a bit (pun unintended) confused. Yes, there was a minor chain split or fork at the beginning of August which created a separate chain called "Bitcoin Cash" which lots of miners switched over to from Bitcoin.
As of today, the price of Bitcoin Cash is quite stable, but no one knows where it will be even next month. It is currently about 7.5% the price of 1 Bitcoin.
yup... very confusing so many coins in the market... also dont know which is the suitable coins to invest in...
As responded by the bitcoinmaniac52, the split was regarding blockchain which created two different chain and there was a new coin called as BCH. It generated as new altcoin and stays on the blockchain and followed by some of the miners in the world.
Speaking about your second confusion that is which coins to invest in is very general question and you can find many interesting ways of doing this in service discussion section where people are asking about this lot of time.
In general you will have to study if altcoins and ICO from which they are generate. Different project has different agenda and that can be used to know which coin would be profitable to invest. There are lot of things you need to consider so go ahead and keep reading about it.
