Protoshares is an ETF for any DACs Invictus is going to release. If you have PTS, you'll be able to claim your BTS by importing your protoshares wallet into BitShares.

BitShares will be Proof of Stake only, no mining.

...rather if you HAD PTS at the 28th of Feb.

This is a good introduction https://bitsharestalk.org/index.php?topic=889.0

So I was mining PTS and no I can't make head or tails of this BTS X thing, is this a new predessor to PTS?

Will we be GPU mining BTS X? If so when is it being released?

WTF is a dac? I read the "Wtf is a dac" thread but that didn't really help.

Should I be ready to start mining BTS X? Is a gpu miner in development?
