I wonder if any one here already withdraw from this website. Any reviews and feedback?
Take a look at their own recent payouts page: https://getcryptotab.com/en/journal/
All the payments are in the thousands of satoshi. If they are a legitimate service that is actually mining bitcoins with your computing power then it'll just mean that your computer is getting severely lagged and overheated for virtually no rewards.
Also, your electricity costs will pretty much not going to be covered.
You made a good decision to stop using it. There are no benefits whatsoever, especially as it could even be a hidden virus or not even pay you when you have just made enough for minimum withdrawal.
