Any tip to synchronizing the wallet? my wallet stop 23 weeks behind and has 8 connections..

First backup your old wallet.dat and insert in the new one, this will solve your problems. I do not see purpose of using old wallet now.

Man CANN maybe has been forked like a hundred times, so how choose the right chain?

If everybody use new wallet then all will be on the new fork, no problem there.

Will else pump or it is dead coin?

Pump was so sudden, and for many was surprising so now price must correct. After weak hands throws their opportunity we will see new pump.

i had DL the new wallet, use the bootstrap file...but after 4 full day i still in synch (30weeks lefts)
