For sure we must know that what we are investing in and how it will work for us, we are making investment means we are putting our money on risk so to get success we must have good knowledge about it and never be doubtful about its profit. Patience is the best way to have profit in your investment, time of investment matters so just buy when the price is low and never panic.
I commend the "patience", it is very crucial to any decision you make and will make. But knowledge is worthless if not taken into account. What I mean is, you yourself should be mindful about it, realize how, where, when you should use it, i.e. be wise.
do not invest if we are doubtful about a project, it will not make us a mature investor. and such behavior is the same as gambling. therefore confidence in yourself in analyzing is needed to become a wise investor, so as not to lose the capital we have. but if we get the wrong analysis, don't be frustrated for too long
I have another solution, do not invest in these projects at all. These days, it's
once in a blue moon to discover such an interesting and profitable project. Even if you're being meticulous, most of the time these projects are either good to be true (scam) or just overly hyped--that will tend to fail sooner than later.
