RE: When you bought or invest in crypto !
There are people who know crypto, but there are so many who don't (yet still comment on it) that the good ones get lost amongst the bad.
I strongly disagree that the old school financial and trading experts know crypto. My experience tells me the opposite. Crypto does not behave like traditional stocks and commodities. This is a fact which they seem completely incapable of "un-learning". They try to apply their market knowledge to a blockchain based tech in the early phases of adoption and fail miserably. I find very few of them are willing to buy crypto at all, they are normally dead against it; thereby demonstrating their complete misunderstanding of the crypto market or their inability to even trade what should be a great money making asset due to its high volatility.
Just look at Warren Buffett or Jamie Dimon for perfect examples of what I mean.
