How can we earn bitcoins and ETH on tor browser and if there is free alt why please share it also. But no illegal thing.
The TOR browser is just that a browser, you can use any browser to try to earn bitcoins or ETH, however the TOR browser can access .onion sites which are known to contain highly illegal stuff, so if you want to stay in the clear avoid .onion sites and try to make that money on the clearnet.
