I hear you - and I think with hindsight it's definitely been the case recently. (I started ordering Ethereum mining parts when the price was $53 and it's gone up $300 while I've been waiting for some of the parts), however giving advice for anyone that has no clue what it's all about to "just jump in" could end up with people risking/losing money they cannot afford out of their ignorance and fear of missing out - which is where all the proper traders make their money. Tell the desperate people to buy so your price goes up and you can take profit, so there should always be some cautionary "do your own research" advice along with any 'get involved' comments.
