I don't have a lot to say here. The most Bitcoin I ever earned was no more than 3 BTC.

In the past, getting 1 BTC could be said to be easy using the method you have mentioned. If you think about it, expecting the ease of getting 1 Bitcoin in this way is no longer easy, so I thought that in the midst of our knowledge about Bitcoin, we wanted to go back to the old days.
If you want to say regret, everything has been missed.
