Theoretical question for the knowledgeable people here: so after a hard fork we will get 1:1 coins in BTC and BTU but the current value will split in half so we would have 50%:50% in BTC$. What if a lot of people would want to sell their BTC or BTU coins so that they get their 100% in BTC$ pre-fork back? Would that mean an impending crash on either the BTC or BTU market or even both due to flooding with old coins and saturating the market and effectively decreasing the demand?
I don't deal with ethereum so I am not aware what has been happening with the ETH fork and its price markets.
