With Bitcoin and so many alt coins, we see many hash algorithms, I'd like to see what is your opinions on which is the best algorithm?
- SHA-256
- SHA-1
- SHA-3
- Scrypt
- X11
-...

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

There is no best algorithm because all are sufficiently secure. Also, the fact that (for example) scrypt is slower that SHA-256 doesn't make it any better or worse.

You might say that one is "better" if it is more ASIC resistant, but that still depends if you think that ASICS are good or bad.

Best is completely subjective and opinionated. There is no best - choose one which suits your needs more appropriately than the others.

I my opinion, i believe all of them are the best, since they are all secure.

For sha-1, weaknesses have been found so I wouldn't pick it as the best.

You can pick anyone of the rest as the best, depending on your goals.

I agree unless you say about ASICs. Its just a matter of time if an asic can be developed.
