I did not look at the data, I am going by your figures and was surprised at the 1.5 BTC you mentioned. If you are right, he was making over 500 BTC per year and that is simply unbelievable. Well done to Daniel of course if those are a fair reflection of BTC he is making. I had no idea the profitability for the owner would have been that much.
It's even more impressive that there are some players on bustabit with as high net profit as 468 Bitcoin, 279 Bitcoin and etc. But there are also some with as low total loss as 1,278 Bitcoin, 726 Bitcoin...
To be fair, it's very sad to see bustabit being sold. It's impressive that website was generating 1.5 Bitcoin profit every day, it's just 77 477 USD per day at the moment. Imagine, you can buy a 100 sqm house in my country with that much money, imagine buying houses every day... As Daniel said, he should be in a point where money is secondary, it's just very sad for me to see another website from my childhood memories, that was looking the same for a decade, is changing hands and probably will become visually a completely new website. I know that will be done for better but I feel very nostalgic when I visit bustabit.
