Dumping your bts v1 to others as fast as one can is not fair for others that may not follow these forums everyday and may have open orders at ridiculous low prices. People who don't have problems with their clients will transfer their bts1 in the exchanges after the snapshot and dump to people who don't know what is happening, while others will struggle making their client to work in order to do the same..
On the other side I do agree that maybe both versions can survive so having bts1 could not be entirely worthless after bts2 but judging at today's market cap i don't think this will be the case..
Having said all that I think we need a clarification regarding how this is going to take place so we have all the same opportunities and choices..In order to avoid complications and people moaning around later on I am personally in favor of bts1 to freeze forever once bts2 is share dropped so not anyone can dump shares to others.
Exchanges need to upgrade, and use only the new BTS 2.0, and not use the old version anymore. That is the point of the 30 day announcement to get exchanges to upgrade.
It would be seriously damaging to the future of BTS if there were two different versions running around, and the community was split. (Just like if Bitcoin XT came out and was only accepted by some of the people and exchanges, and both it and original Bitcoin were both still around).
When you fork, the whole community needs to get behind one fork.
