Wow, that was really a good income from both bustabit and bustadice. I was planning to invest on it but doesn't know how to calculate possible return this was really helpful for me.
Think about it this way, if you invested 7 thousand dollars into bitcoin at the start of the year and got 1 bitcoin. You would have 1.3 bitcoins right now and that would worth ~$33k right now. That is why investing into bustabit is great and it will always be great, plus it gives you hedge against the drop as well. Let's assume the price dropped right?
I would only have to make that back from here or I could at least make some of it back. So, if there is some increase in my profit here, but the bitcoin price drops a bit more, I would still be down but I would be down less than other people. I haven't invested into bustabit all that much, but from now on I am going to start, and with the off-site now being not available I believe it is time for the onsite to get a lot more famous as well, no matter how much bustabit charges, it is still going to be profitable.
