Haven't read all the posts so it may be mentioned before. Current PoS implementations use some sort of wallet weight as a way to handle competitions for blocks. Wallet weight is basically the amount of coins in the wallet. So if I have a big wallet with very small coin blocks (i.e. I transfer the coins in thousands of small transactions), I have the chance of staking a lot of new blocks continuously with the full weight of my wallet each time. That's the problem.

I have 1% of all stake in 1 wallet. My chance to generate a block is 1%
I have 1% of all stake in 1000 wallets. My chance to generate a block is 1%

I see no problem here. (Nxt)

edit: I guess what you meant is:
I have 1% of all stake in my wallet, and I transferred it there in 1000 small transactions.
I still don't see a problem for PoS.

Yes.

Your chance of generating a block is 1%, next block again 1%, next again 1%. That's a problem. The high weight of your whole coins are used for each individual small stake, increasing your chance every single time which makes you a lot more likely to find consecutive blocks at zero cost.

Ideally your chance shouldn't be 1%, the secure way is 0.001% since you transferred the money in 1000 small transactions. You should either have a big block of coins (1 big transaction), so you have a 1% chance ONCE, or you have 1000 small blocks, so you will have 1000 chances of 0.001%. You should not have a 1% chance, 1000 times.

Sorry, I don't get what you mean.
1000 x 0.001% = 1 x 1%
In PoS your stake matters, not your amount of transactions.

Yes, either 1000 x 0.001% or 1 x 1%. It's not the number of transactions, it's the number of coin blocks. Each block stakes once until it matures again (8 hours or whatever), if you have 1000 small blocks in your wallet, you can stake 1000 times right after the other and current implementations give you the full weight of your wallet in the competition for staking, giving you a great chance of finding consecutive blocks.

So basically in simple terms, current implementations give you 1000 x 1%. That's the problem.
