Definitely when price surge fast, the next thing will be correction or a sudden drop in price since those who bought before the rise will eventually cash-out and the cycle repeats.
If this price increase is caused by FOMO then does it mean there are big money whales out there who are moving the market because they are afraid of missing out? I find that hard to believe. FOMO usually works on altcoins where there are many uninformed and less intelligent "investors". Bitcoin's price movement is caused by something else, maybe.
FOMO works on all investors, sophisticated or "less intelligent". Bitcoin has been referred to as mass hysteria in the past.
Big whales do play a part, but what is happening now is all round buying.
Exactly. Looks to me this is a new territory for bitcoin ecosystem. A lot of buying going on a lot of exchanges around the world. Specially in Japan where the trading volume is up to almost 50% now, followed by US and Canada. What I'm afraid of is that the volume trading in Japan is covering half of the volumes. It looks like what happened when China dominated the market then a big crash happened that push the price to sub 900$.
