This is where we as individuals must have firmness in making decisions, we can receive references from wherever we are but do not have to be applied in the final decision I think, so in my opinion I agree with your statement. The best expert will always be yourself. So why waste time hearing the words of experts suddenly when the market is up, and disappear when the market is down
We need to be an expect in anything we are doing so that people will be proud of us seeking information from us..
We need to be ourselves own experts so we can make decisions because in what we have seen and studied.
It is good for us to keep learning so that we are not going to lose our ways at the time when we are supposed to be shining.
Social media is full of lies and the influencers only take advantage of the opportunity they have as celebrities to take good about what they are paid to promote so it is very important not to take any advice concerning the crypto market from anyone on social media cause they may not talk the exact truth because they don't even know. Having a personal research on everything that has to do with informations about the market and taking our personal decisions after much research will help in a long way. Getting more information from any knowledgeable person with good proves is not a bad idea but the conclusion should be based on the investors decision not the decision of an expert.
Now, it's best that we learn it from different sources, apply what we learn and add or subtract to improve it and be able to achieve our success. If it's an external signal, go to charts and other economic sources of analysis, do your analysis and compare and contrast before you welcome any financial market ideas.
