Pdata announced buyback program. They will buyback 1% of all your tokens. Do you know the result? -50% drop 
. I do not think that this is the best way how to protect against dump.
PDATA was doing a very wrong thing, the dump caused by PDATA didn't make its investors feel confidence by release the regular update. the buyback should be more than it. but PDATA team is really bad at this moment. . I do not think that this is the best way how to protect against dump.
