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 is a scam one, and I can not forget how it dumped days ago. Buy back usually help price increases, but it does not right for all cases; especially with scam projects. When investors find the truth about scam projects, buy backs don't have good effects on price.. I do not think that this is the best way how to protect against dump.
