He or she has to actively watch the market to not miss such an oportunity. Not everyone is doing that.

I was one of the lucky that hesitated with swapping my BTCD long enough and yes I have sold every last of mine during that pump although with a little bad feeling because the last thing I want to do is pulling ppl over the table. I just hope that I sold into the bad ppl hands makeing them pay a lot with their markt manipulation and not hit some newcomers with no experience that fell for that strange and unexpected pump.

I am surprised to read that the swapped BTCD are not burned and could be put into circulation again. Is that so?

You will not have a big choose. If not something miracle strange is going to happen, like that unexpected BTCD pump, BTCD will be worthless after that swap periode is over and most likley the network goes dead. Once it dissapears from the exchanges it is over.

Sad I too had liked to see SuperNET with BTCD comes to life as once planed... but that is not going to happen anymore. Hence the reason to keep any BTCD is gone.
