2 of those links don't say anything about Protoshares. The 3rd link still shows people expecting future sharedrops at the time I bought PTS. There has never been a sharedrop.
Try to keep an eye on the links you recommend to other people.
you're responsible for following your investment.
That is true, I was new to crypto last year and I got fooled.
Protoshares merged with BitShares, but PTS continued to exist.
Invictus promised to drop shares to PTS - "but we don't call ourselves Invictus anymore".
I bought PTS at Poloniex - "But now it's BitShares PTS, formerly Protoshares, so technically nothing that was said about Protoshares still applies."
It was dishonest to allow a new coin to continue under the ticker PTS, appearing to be the same coin.
I actually thought Cryptsy was dishonest for "not honoring the sharedrop" - but Cryptsy was the honest one by not pretending that the new PTS was the same coin as the old PTS. Bter and Poloniex allowed people to keep buying a defunct coin "because a new sharedrop is coming", and that's why I bought. But the only sharedrop was itself, and then there's never been an actual sharedrop.
