Why not try for yourself? It is not that bad to invest in casino's even the returns and profits are not that high but if you want to diversify the bitcoins you got. Investing in casino's is one of the best investment so far, just choose the casino's that are reputable and has good record from their early investors. Try it for yourself.
the ROI will not attracting you but at least provide you a promising profit compared to do business by yourself.
the risk lower than have to gamble by yourself or do your own business, especially in casino investment where there is few case casino bankroll down to zero.
We should really not expect high returns because others think that investing in casino's are guaranteed to give them good profit. They may give good profit but the sad thing is that it is not that high at least that is good profit because it is a legit service that casino's are offering to us to be part of their operation which is a good thing.
You can earn big in a casino if there are plenty of high rollers on the site. But there aren't that many high rollers in any site. But in the long run you can still earn quite big if you just leave your investment in the casino. Probably a 20% per annum is possible in investing in casinos, that's quite good. But I am not sure if the casinos will really last that long.
But we can't guarantee that there are always high rollers on the site. I can think that there are some other ways of earning through casino's and that is when we are going to maximize your bitcoins on investing on different casino's. 20% per annum is already a good return in casino's because we know that their income is not always that good too all the time.
