1 - new ETH will 2 in per block, this is good. (circulation suply will grow less then now)
2 - (PoS) algorithm. i think SEC and PoS arenot friends
1. i don't know what you mean by this! but if you meant ETH will split into two "chains" then that is a highly likely outcome of this hard fork. but you have to know that it will double the coins not your money, the total value will probably be a lot less than the current price.
2. no, SEC doesn't care about PoS or PoW. what they care about is that ETH is centralized and manipulated so much that it has turned into a pump and dump scheme.
