Usually you can trust ~50% of the information in popular 'specialty' subreddits, but the crypto subs are straight up useless beyond major headlines. Even then, the discussions are 90%+ trolls and shills and 10% memes. Steem and Bitcoin Forum have been better, but all around the larger problem is that things move so quickly that the information you're looking for is probably no longer accurate.
The chaos is one of the most interesting factors for me. It reminds me of the internet circa 1995 - you have to do your own research, estimate/predict larger trends in information flow, and have a finely tuned bs meter. The biggest barrier to entry is that no one is trustworthy, so even your tools need to be properly vetted or self-made because unlike the 90s internet, the thrill of finding a vulnerability may carry a substantial reward.
I do think there is a legitimate opportunity in the crypto space and 'believe' in the underlying tech. You just have to ignore all the folks building their rockets out of lead and toilet paper while rofling about their moonshot, sneak past the whales, and slip between the trading bots.
One other interesting aspect I don't hear mentioned often is how this comes on the heels of the Russian election meddling and the similarities in tactics. If crypto has any real immediate use for the average person, it's a good way to gauge how susceptible you are to propaganda. Invest (enough to sting if you lose it all) and see if you can turn a profit. Force yourself to put part of that money into an obvious scamcoin and keep track of how you relate to discussions surrounding it. Crypto can be a psychological playground if you let it.
