2013 was a (big) peak also, it was on the national news that year and they spent 15 minutes discussing BTC even various alt coin protocols and their implications on national TV news discussion programs. In 2013 BTC was already 'old' though its continually a growth product it was already represented in all the various sectors at that time, good and bad. It went into a lull after the '13 peak and then obviously its come back which surprised many in its ability to do so.
Yet again in 2019 somehow it was a surprise once again when it rose, I relate it to FED policy and various other political maneuvers in each country vs the people and the concept of capitalism which is a stranger to us and somehow could be exciting and new to someone of the newest generation.
Its not unreasonable to consider the echoes of 2013 and how it relates to now, though its ancient history in technology terms and obviously difficulty rose just a tad and I wont be mining on my GPU. I guess the dynamic that will always repeat is the human and genuine economy or market type phenomena. To the truly cynical, everything is a repeat :p
The closing odds is what really matters; before that, the odds shown are only an estimate and likely not very accurate.
I've seen this before and it was kinda really bad for the website. Shame as it was a great esports betting site but everyone piled on their bets at the last possible moment before the game start which with a small site would swamp the odds from one extreme to another. I won with like 80 to 1 odds once, my judgement was good (+luck) but it was down to somebody misjudging the weight of their bet vs what was in the pile; even if they had been correct and won the payout would have been silly low returns.
Unreliability discourages people from betting in future as one side gets bad odds or not the return they expected. This current system on Freebitco is quite possibly required even though its a giant site compared to the one I remember and the numbers helps, some of the bet outcomes are slim or eccentric perhaps.
I think every system has some relation to positive or negative feedback loop, some kind of adjustment to a cycle can be helpful. This relates to BTC also, nobody expected that some dude 10 years ago could devise a self adjusting system and every economy to some extent wants to destroy itself - call it greed or whatever if you like. The FED will fail in their endeavours its quite certain, its not my wish especially.
