Just for some extra clarity..........
For consumer level users: make sure that you (or your wallet provider) ~~are on Bitcoin 0.9.5 or later, and wait for 30 confirmations on your transfers.~~
For miners: stop SPV mining, validate everything or lose income.

(and, obviously, transfer all your BTC into nice stable NXT....... Grin

)

Consumers on 0.9.5 or later are safe an do not have to wait for 30 confirmations. This recommendation is for SPV/web wallet wallet users who are unaware which version they are connected to. Most web wallets and SPV wallets are safe in reality but users should either check or wait 30 confirmations.

This is a large warning to users to not only be careful and skeptical about bitcoin but be that more careful with using any alt as they have a small fraction of developers debugging , testing and warning users compared to bitcoin.

So this will only potentially effect people who are making transaction, sending & receiving coins atm?
If I'm a simple HODLER & haven't & won't be buying any coins this weekend I'm safe & ok yes? My BTC's in several wallets & paper wallets are ok & I can totally ignore this?
Thanks in advance to anybody who responds.

This only effect Bitcoin users using a node that is 0.9.4 or earlier whether directly or through an SPV /web wallet. The only risk they have is if a malicious attacker tries to double spend with them. To avoid this check with your connected node to make sure you are up to date, use an up to date bitcoin core node, or wait 30 confirmations.

There was never any risks to you losing your coins in paper wallets or cold storage even if you started up an old version of core.
