2. ETH devs cant even get PoS working on their test net. You *might* see it by 2019 at this rate, but even then its just a hybrid system that is 10% PoS and 90% PoW still.
3. ETH, ZEC, and many other GPU algos are asic resistant. They are specifically built to not work with ASICs, and devs have come out saying they will change the algo if someone does figure out how to make an ASIC so its not even a concern.
4. ASICs can mine a single algo, but not a single coin. Theres a good dozen coins a sha256 miner can mine.
5. Dont invest any money into mining that you cannot afford to lose. Mining takes a large investment to properly get started. You shouldnt be mining and exchanging all of your coins, you should be mining and hodling as much crypto as possible. This is not a short month to month profit game, this is a long term slow play kind of thing if you want to make any real money.
^^^everyone read this carefully.
also, I had no idea eth wasn't moving to 100% pos. can you show me where you saw that? it seems like there's no point to making a change like that, why not just keep it 100% pow?
