You got a point here, people who is not rich cannot guide others to be rich. But then again, we do not know each others personally. You might be wrong too. These people could also be rich and just riding the tides of bitcoin. They could be giving away precious advice for free and you are just too proud to admit that they are right. There are some valid advice here that we should follow. You can filter yourself what you want to listen and not.
And people tell themselves money doesnt define a mans richness. In a perspective yes, but practically we all need money to survive and especially the ones with families. Values and attitudes are some of things that go with richness.
Btc might not make you rich it but its a good head start for people who have yet to find a job. Respect btc.
