Hi I am new bie , How many sub part of bitcoin will be released like bitcoin core and bitcoincash  etc ?

If you mean trading range of bitcoin .  Than It is the end of crypto-world, virtual and imaginary things dont last long .  I hope as it rose to nearly $20,000
Now with same speed it is coming down. Hope to hit down target of $113.  

What about funds that were not stolen and are still in exchange wallet, 13onTj8LMdASpcxCoxtjr6Rp6hwLTfwR2s
