What do you guys think, will it still be worth it investing in expensive hardware and high electricity bill?? ;D

.

Yeah, they still have some but soon most of them will disappear as people move to more efficient systems. Yet some popular like Bitcoin, Litecoin and privacy focused coins like monero may survive longer. Ethereum is soon leaving pow.

I think POW will be around a long time.  As the overall market rises more and more people will start to look for more efficient ways to mine, like converting to solar.  Every so often a solar post comes up. 

POW is probably here to stay. By the way, there's a new POW coin called Lynx - it is made to mine on a Raspberry Pi, so electric is about $1 per year.

Here's the ANN: https://bitcointalk.org/index.php?topic=2912479.0

I don't think PoW ever stop. First of all Bitcoin is PoW and it won't change until all blocks are mined (in ~2140).
Ethereum will switch from PoW to PoS, that would affect gpu card industry, electricity, wind and solar energy industry etc.
I don't expect too many home users that would make mining in PoW in the future though. It will only be industrial mining, probably.

POW remains novel and useful, and apparently most of the mining is run on hydro, which is a highly renewable resource.

POW will never die. There are so many new coins going back to even CPU mining. Many new algorithms go to spend as little electricity and resources as possible. Some miners are mining multiple coins at once using the same resources. The real question is whether POS will survive? For most POSs should have thousands of coins to get 1 coin per day worth no more than $ 1.

 I personally think POW mechanism is better, because it need not spend a lot of manpower and electricity in token, but POW mechanism is faced with a very serious problem, so any one can issued a token, the cost of fraud is too low.

yes because unlike what you may think, there is not a good alternative for PoW created yet. they advertise some stuff that can be better but i have not yet seen anything that is actually better.

and it is not expensive and your electricity bill will pay for itself because you will be getting a reward for the "Work" that you do.
in fact PoW is the best method of distribution so far. the rest of them are completely unfair distributions.

Future for POW only? I doubt it. A mixture of PoW and PoS - i guess yes. Examples - Bitcoin, Ethereum, Vericoin/VeriumReserve. This will be the standard in the next couple of years in my opinion.
