Are mining pools the weakness of all mineable coins ？

[samsss]

just started mining a month ago，found out what a 51% attack is, and pools can go down easyly.I mined litecoin,memorycoin,doge,moon,vert,earthcoin,lottocoin.few big pools have most of the hash power.Lets say 3 biggest pools have 30% each.One goes down ,not a problem.what if 2 of the 3 go down

NO

Stop making thread, Spend at least 2 months of reading and searching.

Stop spamming using your low intelligence and do research before you talk about something you don't even understand.
Pools don't go down that easily.

A pool going down won't 51% a coin, but anyone controlling 51% hashpower can 51% attack a PoW coin.

If you're concerned about the centralization of hashpower, pure PoS coins, like Nxt, aren't susceptible to 51% attacks.  Nxt is resistant up to 90% currency concentration.

Don't forget about p2pool.  You get many of the benefits of pool mining while helping to protect from a 51% attack.  And you should end up with more coins because of lower fees.

seems like you misunderstood "51% attack".....
It will be a problem if 2 of the 3 big pools "co-corporate" with each other and controls 60% of hashrate, but it will not be any 51% attack if 1/2/3 big pools go down....

The only possibility is like in this example:
4 pools control 25% of network hashrate each. 3 go down, which would mean that the pool left controls most or all of the hashrate.

True.
The only problem with p2pool is that, you need to have decent hashrate, or the variance will be pretty high.
