Cryptotab is one of those apps that is going to waste your time and resources and make you think you are making some sats and yet you wasted a lot.

Here is what you need to know

3. Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs - https://en.wikipedia.org/wiki/Application-specific_integrated_circuit . You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware. You will not find software in this section to help you mine bitcoin in this absurdly inefficient manner in this subforum. It would cost you thousands of dollars in electricity per year to earn only a few cents in bitcoin. Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today. Any discussion outside of ASIC related mining, except in the interests of academia, will be moved to the altcoin mining section. There isn't any point attempting to mine bitcoin with CPU or GPU even in the interests of learning as it shares almost nothing with how bitcoin is mined with ASICs and will not teach you anything.

TL/DR Summary:
- You CANNOT meaningfully mine bitcoin with your PC or laptop no matter how powerful it is.
- You CANNOT meaningfully mine bitcoin with your tablet or phone no matter how powerful it is.
- Mining apps for your phone or tablet that claim to mine bitcoin are almost certainly scams.

great, thank you. so.... that is why I am wanting to upgrade. Any thoughts on the miners I mentioned?
