I placed some in an exchange to have access away from home, but could easily send them back to my wallet. It should be easy for anyone to prove they did not dump the coins if need be. If they did dump then I guess they better start buying back at whatever the cost
On a serious note, I can't speak for the devs but it does seem they are taking great measures to weed out abusers. Round 2 should leave us with an even stronger community.
But why did you even placed them to an exchange?
The only reason, because you want be able to sell your coins as quick as you can when the price is rising?
Actually, some of us use exchanges for other reasons than dumping.
I have 90% of my coins in three exchange and only trade with a couple coins. The rest are just in storage.
First it is convenient, I can access my wallets from any computer. Not every coin has an online wallet service.
Second I just don't trust the computer I am using. It is an old XP machine about to die on me.
You might be right for the most part, but there are other reasons people transfer coins to an exchange.
(there is a another method to import a address into a preexisting wallet too...)
