Cannot update to the latest version :

Quote
EXCEPTION: 11DbException
Db::get: Cannot allocate memory
worldcoin in AppInit()

terminate called after throwing an instance of 'DbException'
  what():  Db::get: Cannot allocate memory

With ~ 29GB of free memory, I don't think it's a memory problem

P.S. MCXNOW feeshares are now being sold to the public, get them while they're hot!

so 5 posts, praising realsolid, pumping worldcoin and mcnow fee shares
are we to assume this is a realsolid shill account?

secondly, it's more than a coicidence  worldcoin is being pumped on that exchange before the new site launch
then this 'application' sent to trade worldcoin has all the hallmarks of what mcxnow just did, fee shares, on a site with no indfo or history, and under privacy
scharmbeck.com

can we assume realsolid bought or took over worldcoin and is his latest pumptoy?

please also point out to noobs, there is over quarter or a BILLION of these worldcoins
265,000,000 I think

There are only 28,463,236 WDC in circulation right now.  Let's be sure to use easily accessible facts when making statements.

Amazing how it was detected only by and fixed by Realsolid.

The announce thread reads like a marketing spiel for mcxNOW.


Great job RS, you stopped your own attack!
