The bull run will surely expose all of them, trust me, some of them are smart enough to understand this and that is why they are trying every means to fool making unrealistic promises in order to dump on you.
I agree with you, every one needs to be extra care when making investment in this volatile space especially in a bear market condition such as this. I always believe it's not only about taking huge risk but taking well calculated risk is the key to success, we are indeed in trying times and most projects even the guenuine ones seems to be doing less than expected but the bitter truth is not all of them will see the end of the tunnel, we've seens many of them gone already using the excuse of the bear and so will many when the bull set in so the advice is everyone should invest wisely
