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 ).
Before you jumping into mining please do your own research, especially about ETH mining, check the
roadmap for ETH development, make sure you know more than what mining calculators telling you. Learn about
ETH2 ,
EIP 1559 ,

6174 and
6174-A also ... Its a good thing to know about
Tax ConsequencesThe big brother is watching you, and not just in the USA.HAPPY MINING to all of you and good luck with your new adventure
I DONT UNDERSTAND WHY NEWBIES KEEP ASKING THE SAME QUESTIONS " ITS TO LATE TO START MINING , IT IS STILL PROFITABLE ? WHY MY EARNING IS LESS THAN ALL THOSE ONLINE CALCULATORS TELLING ME? WHAT IS THE BEST COIN TO MINE ? WHAT IS THE MOST PROFITABLE COIN TO MINE"No one can tell you !
Always going to be a 2 group of ppl who telling you it's ok go for it , or don't bc you just wasting your money and time !
You have to make a decision for yourself !
Do your own research !
No one can tell you for sure what's going to happen with cryptocurrency !
No one can tell you it's going to be profitable for you or not !
No one can tell you how much profit you going to be able to make ! ( if you can make any at all ) No one can tell you the ROI ( return of investment) time !
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 calculators you are seeing on the web can tell you what's coming tomorrow , months later or 6 months later !
Those calculators telling you about today , at that moment when you typing in your information !None of those online calculators calculating pool luck !
None of those online calculators calculating your stale/rejected or invalid shares !
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 !
! INVEST WITH THE UNDERSTANDING , THAT YOU COULD LOSE EVERYTHING !
