There is a member here that has been doing that. My take was he bought tons at 1sat, "revived" the coin that the dev skipped on, and profited. I will try to find it again.
edit - I must have dreamed this. I can't find now. I remember the member had all of the coins they revived in their signature.
Not a dream - check sig -
https://bitcointalk.org/index.php?action=profile;u=158610He/she is dev for sherlockcoin and has been involved with revive of 5 other coins.
This dev is trying to revive both astrocoin and beecoin. They are both dirt cheap right now and I was wondering whether to invest in them in the hope the dev's work will raise their value.
However, androids tokens was revived by a new dev team and it has gone down in value since then. The devs did a great job but maybe the falling price of bitcoin drove androids tokens price down.
All the alts seem to be falling in value and I'm just not sure if astrocoin and beecoin stand a chance of rising in value.
