For me, I have been in the space since July last year so, I went through the big China FUD and the December bull run. Other than that, I have no prior experience. We can read archives but that's not the same I guess. 
Same for me, came into the space at about the same time, around June ending. Experienced a lot within a short while and it was a new world to me altogether. I belong to some crypto groups on telegram and whatsapp and all the early adopters on those platforms tell is how much they regret the fact they didn't buy as much Bitcoin as they could at the time as they didn't know it would be something of much worth. As regards the similarities of the current market situation and that year, none of such info has come to the fore.
