True, I should have made that kind of investment. But it's also easy to say that today.
Anyway, I made the investment that I thought I should make at the time and that I felt comfortable with. Because any investment we make, we must always invest an amount that we feel comfortable with.
Logically, it is now much more difficult to reach that amount. I don't regret it... actually, I regretted not having invested more in mining at the time, it was something I always wanted and never got. And now it's even more complicated.
