I think green profit is a good sign or positive sign. Meaning the trend is going up. You can have it converted into local currency to enjoy it. Or hold it and wait for the time that the price will be going down to buy another and sell when the price goes up again.
Green days is really the best thing that can happen to your portfolio, its gives you so much happiness. But you must focus first on your goal because if you so much profit therefore you will gamble more so better to assess well your goal. Green days is not healthy sometimes because greed may take that away from you so better to be more careful.
Green days doesn't mean that you are a lucky person, it just happened sometimes that you have a green profits in gambling because you've got lucky, and you must be aware of your greediness in money, it is not good, trust me. Craving for more winnings in gambling is not healthy for your money, I'm not saying that it is no good to crave for more, but not in gambling.
Why would it not be a meaning for a lucky person to be lucky at that time? It is very well lucky to be raining all the time because that doesn't always happen especially if you have experienced gambling itself. It's the greediness that needs to be controlled just like you said because it won't save you any money and it wouldn't do you any good.
