Posted this topic almost 3.5 years ago... There is the brand new, 2021 updated version 
There is the Original Link for my topic from 2017 HEREThe same thing happening now what happened in (2016) 2017, ppl got crazy about mining, investing money into GPU's, ASIC's, hoping a big profit in a short time, GPU's, ASIC's price are crazy high, but really no one know what's coming in the future.
Lot of us know
what happened in 2018, some of us was able to make a great profit with mining ( mostly those guys who started mining before crazy GPU prices ), and some of the unlucky ones come back to this forum and cried for they Money, said just bad things about mining ( mostly those guys who paid 3x, 4x, 5x price over a RX480/580 MSRP ( manufacturer's suggested retail price ).

No one can tell you what is the best coin to mine !
No one can tell you what is the most profitable coin to mine! Coins profitability always changing, what is best to mine today, maybe going to be the worst to mine tomorrow !

None of those online calculators able to predict difficulty growth !
None of those online calculators can predict what would be the coin/$ exchanges rates a minutes later, a hour later, tomorrow, next week, months later, 6 months later or a year later !
It's little bit of gambling , you must to decide you want to play on the lottery or not
YES some of us got lucky , made some money with mining
YES some of us got unlucky , lost some money , bc when price started to fall , sold they coins , miners...
! INVEST ONLY WHAT YOU'RE WILLING AND ABLE TO LOSE !
