i have discovered a flaw with current PoS implementation

you can easily do a 51% attack with PoS blocks without needing large holdings

since PoS blocks are generated on a coin age basis, you could create TXO's delayed by a time offset at the minimum TXO cost for a future attack period

so after creating 10000 TXO of 1 MINT separated by 0.5 seconds to make sure 60 consecutive blocks are generated at repeated interval by your wallet 20 days in the future, the attack would last 1 hour and 40 minutes

enough to put the security and function of a coin in question

couple that with the fact the difficulty calculation includes PoS blocks, that would mean difficulty would jump to stratospheric levels making it impossible to mine PoW blocks

No. In order to get 60 consecutive blocks you would need a TON of coins. There is no way that 1 mintcoin will produce enough coin age to overpower the network's coin age for 1 hour and 40 minutes. 1 MINT all alone by itself would probably take years to successfully get on the blockchain.

wrong, only the calculation for how much coins you generate uses coin-days
valid block generation only uses coin age

There is more to it than that. Getting each consecutive block is not that easy.
