There is also something else different than in late 2013, is that it's been more than a year that mining ETH is profitable. And guess what? Last year (in feb) it was the same talking, don't buy GPU ETH will go POS soon and so on..
In fact, it's better than last year, because we have far more option to mine (ETH, ETC, ZEC, ZCL, LBRY, UBQ, etc)
yes and one reason is more then 16.3 million btc coinsare in wallets and a simple password releases them...
So a vast amount of wealth is easy to trade an alt coin for a piece of a btc coin.
consider this Nvidia has the ability to pump Zcash from 295,035,556 at a price of 209 a coin to
600,000,00 at a price of 420 a coin if they choose to do this.
Think of the frenzy for nvidia cards to mine Zcash.
I think people simply do not see the wealth pc companies have to compete against asic mining by making gpu mining worth while.
Intel---------cpus
Amd---------gpus and cpus
Nvidia------ gpus
Asrock------motherboards
Asus--------motherboards,pcs,gpus
Biostar-----motherboards
Gigabyte---motherboards,gpus
Evga-------motherboards,gpus,psu's
Msi---------motherboards,gpus
Dell--------gaming pc's
HP---------gaming pc's
Lenovo----gaming pc's
Above is small part of the list of companies that want gpu mining to work.
compare to Bitmain,Bit Fury, Avalon a few others building Asic gear
which side has the real $$$ pc+gpu's side has the money not Asic
