You cannot mine coins with a laptop and expect "profit"
The problem with mining is and has always been HARDWARE, If you can find it
You can buy Antminers on Bitmain.com. Before you do, determine your break even point (how many months)
AND your electricity cost (double the cost in the calculators because you must COOL the machine with AC
after you have heated it by mining)
Otherwise you need GPU cards. Check the prices on newegg and calculate the break even time and you
will see that it is many months to break even.
ALL MINING IS A BET. You are betting that you can mine and keep the coins until the price goes UP and that
your equipment does not fry from running it 24x7. If the price goes down, your ROI may stretch to months or years.
If you can keep the coins long term then your only risk is the hardware cost and a bit of electricity.
Example - On Bitmain.com today - Antminer S19J Pro - Bitcoin miner - 104 Terrahash per second - $11,024 USD

3KW power consumption and $0.05 for electricity (this is a commercial rate) gives $19.61 profit per day
The break even point for this machine is 562 DAYS.
That is a LONG TIME
Sincerely,
