CryptoTab earnings decreased !?

[mohsenz2006]

Hi
I've been using crypto browser for a couple of months and I was ok with it. My CPU could mine about 0.00004 bitcoins per day. (Not too much but it was ok.)
Unrill a few days ago wich my earning reduced significantly and now it hardly reches to 0.00002 bitcoins per day. Most of the days it is below this amount.
I should say that the hash rate is the same and has not changed since I started mining and I have no referrals yes.
I really need to know what is going on and why my earnjngs has reduced.
Please help.
Thanks in advance.

The block reward is fixed at 12,5 BTC (+fees), so as the number of miners increases, the share for each miner decreases. This effect expressed by the "difficulty" value. Here is a chart of the difficulty over time: https://www.blockchain.com/en/charts/difficulty

Either way, mining on a PC in a browser is an incredible waste of money.

The more people use this service the lower is the payout per user.
Anyways, its not very smart to mine BTC that way. The costs for energy running your PC is way higher than your return, you are literally burning money!
