This is the second or third time somebody got so lucky with ridiculously unlikely odds recently. Some people have all the luck but it’s just a lucky streak, a freak occurrence. Please don’t start thinking this is possible for you because it’s very unlikely.
Let's just think it's just a kind of lottery in the mining industry where only a few people have won it. As simple as that would rest your mind and not get a strange idea that you could also get those lucky blocks. Nevertheless, if you won't have any problem with your electricity bill, you can try to mine too if you have enough components but if you don't have anything, then it's better to stay on daily trading where the profit is assured.
