He's lucky he didn't get wiped out, but he bought at a good time in terms of what the general sentiment was around then, and where Bitcoin was priced.

From my perspective, if someone did this today and Bitcoin went to 200k, that would be lucky, because the market is at all time highs, rather than uncertain lows. It is a risk/reward balance, and there is less risk involved when more people are fearful.

The other part of this is capitalizing on a bold strategy and not becoming greedy, which many people tend to do before they lose most of what they risked. He could still lose a substantial amount of what he has, but that is part of the learning process.
