Well, as time goes by there are new people who entets the crypto shpere. So, I guess the FOMO mentality will never get old. As soon as the market price increases in a significant way, people sell out their alts and join the bitcoin train. Of course, everyone wants to grab as much money as they can.

I think this could be the case but maybe we just attract new investors and their money is the reason why the price keeps on getting higher.
We don't really know if it is cause by FOMO or just a huge number of new investor decided to enter the market and that is the reason why the price is going insane.

I don't think it's a case of FOMO, FOMO can't push the total marketcap as high as we currently have. Although we have seen many great news as regards the big institutions entering bitcoin from bakkt features to Microsoft decentralized identity Atop bitcoin. There must certainly be something some of us are not privy to as regards the current market sudden spike. The community members that have any fraction of bitcoin may want to jealously guide it.

if bitcoin price breaks above $10k before this month (May) ends then you can call it a FOMO, but so far  with price reaching $8k with a couple of very good corrections this does not look like a FOMO to me at least not the type of big FOMO that we usually see in bitcoin.

lets not forget all the big positive news that has been coming out  lately like Microsoft adopting bitcoin even more, eBay saying they are going to accept bitcoin payments and a lot more...

Bull Market 

Idk man, all this seems a tad bit sketchy to me.
About a month ago everyone was crying at 3.5k and now we're well beyond the 100% value jump.

Bitcoin pumps, all the other alt hold ground $wise. This doesn't seem like an all out FOMO stage yet.
Besides fidelity... there really isn't much else going on. Miners are going to be profitable again so we should see increased selling pressure.
Halving is over a year away.

I'm going to throw out my prediction: Might hit 10k, but ultimately I would believe $5k BTC is in the future. I see a rock dropping soon.

FOMO? Not yet for me because if we are now on that stage then we can see big spikes due to whales entering. Anyway, the market for me seems stable because it only creates a horizontal-like zigzag pattern. Meaning, there are people who invest, some sold and take small profits on fluctuations and buy again. In my opinion, I like this more kind of trend compare to a roller coaster ride because it offers less pressure for us. You can sleep well at night without worrying that price might drop hard all of a sudden .

Anyway, if you were an investor who still hesitate whether to invest or not, do it now because you might miss the rocket. I can feel that it will launch soon (I really hope so). I'm not creating hype or whatsoever, I'm just giving my honest advice since I think that another falldown on btc's price is not yet in sight.

I'm glad that I'm not the one looking at volumes as sort of an indication of a FOMO. But damn, I was surprised to see the trading volumes in 24 hours, sure thing, it looks like FOMO to me. Where did all the money come from if not for people who doesn't want to miss the boat? Many will join, the price haven't touch 5 digits, so there's still a lot of chance to get on-board. Probably trading platform using Segwit and batching their transactions or traders themselves are into Segwit that's why the mempool is not that choke as compare to the 2017 FOMO.

Whenever there is some form of growth people fear of missing the chance as it is not promised for a bigger growth or it can fall low. When the price rally keeps going this will be very common among the small scale investors. The cryptocurrency network will be speculative throughout unlike the market trend. As the price keeps growing there will be more speculations than the days of low price which too contributes with the price rallying.

There are many people that haven't even touched crypto and this next bubble will be a lot bigger than the last one.  Greed takes over and people fomo in at the top like always.  People have short memories and don't want t understand the pyschology of bubbles, its why they always play out very similarly.

This rise is happening too fast, so I don't think it's a mature market yet, we are clearly in a speculative scenario that creates some general excitement feeling in everyone, what makes me agree there is some fomo in the air, helping to rise btc price even more.
