I think none of the above. DAG, while very interesting, has been proven to be not safe by pretty creditable people. The Tangle technology on IOTA has an unsolved attack surface that I will not go into now, just look around im pretty sure you can find detailed information on it.
PoS is also not safe.
Unfortunately, PoW remains the most time-tested technology to keep a ledger safe from being modified, so wether we like it or not, Bitcoin is going to continue being the #1 coin (I say unfortunately because I would like to see an actual contender, but just there isn't)
Anonymity will also be improved in Bitcoin. Recently new discoveries have proven to make CT with only 3x weight of transaction (in the past it was measured to be 16x). At this rate we could have fungible BTC in the next few years.
