what is up with all these new accounts asking about bitcoin unlimited! nothing about BU has changed. it is the same as before and this "split" doesn't seem to be related to it at all.
My understanding in the event of a split we will receive two lots of coin on each chain,
you won't get "Lots" of coin. you will have valid coins on any existing chain. and it will be as much as you had before. if you had 1 then you will have 1 on chain1 and 1 on chain2 and 1 on chain1000
and the likelihood is people will flip coins from the least favourable (BTC Core or BTC Unlimited) and the price of both will go up/down accordingly.
for "flipping" coins there must be a place to do it. it means an exchange has to list them for trading, they have to download the specific other client, sync, change their platform code, do something against replay attack, an a lot more headache and issues then allow users to deposit coins to "flip"
for all that to happen, the other new chains have to be able to exist for a least amount of time and show thy can survive first. and since this is bitcoin i don't really think it is possible.
there is a high chance we won't see any forked chain to survive for long if the support is not there.
My question is
what happens to Altcoins which you're holding and paired with BTC . . . if you want to sell later down the line what do you get in exchange? BTC Core or BTC Unlimited or both?
doesn't really matter first because of what i explained above.
second because altcoins will be dumped hard if anything goes wrong with bitcoin price. you saw a glimpse of what could happen recently when price went down from >$2600
