It depends on the type of advice, even developers may be bad at predicting while traders' advice is bad in terms of account security or privacy, so you should divide cryptocurrencies into several specializations such as investment, security, privacy, and then ask several trusted people according to the subdivision.
some are pro bitcoiners and will tell you to stay away from altcoins.
Yes, i have similar thought about the type of advice to render because the crypto economy is very wide and there should be specialists in every section like, mining, marketing, Trading, designs, ICO/IEO management and community managers etc.
As an economicst, i can give advice on the market, which includes, buying/selling financial instruments, demand/supply and consumer behavior, market trends, Data statistics etc.
In addition, there are actually highly experienced bitcoiners who has been following the Bitcoin trends since it's inception, and i think they give some market advice too.
