Yes you can earn money with this but it depends on how you execute things, You need to have an analytical thing or whatever things that can help you out.
Anyways did some research and found out that you can do three things with bitcoin to pretty much make money.
1st BuyNhold (Will take you years before you even get rich and thats if you put millions into BTC which I dont have) the low low prices are over, which now you require massive capital
And don't just hold on what you buy since there are so many scam coins listed on various exchange and even if you buy bitcoin still you need to act smart to earn since bitcoin is not free from loss, we might gonna break our capital if we are confident to much for a huge pump coming in next following months but suddenly a dump came. So the best to put in your mind right now is to sell when profit is already showing so that we will not miss the pump and earn.
2nd Minning which same thing it is now super complicated to mine just 1 bitcoin its not even worth to mine depending the country you live in due to electricity and hassle
Not worth I agree with that but try to invest on it if you have money to spend on mining since if you buy those quality rigs for sure you will still possibly earn from mining.
