FOMO is short term effect I think, I'd much rather see more solid effects in play like actual usage not speculative holds .
It depends on the speed that is gos and gain on the chart. The higher the spikes the more people will buy inn. We have to wait to see how much steam this bull got
It's still hard to put some numbers since bitcoin just started to increase this month and it still not that fast how it act in 2017 bullrun. The good things is that many crypto investors were thinking of coming back due to this increase. Maybe just waiting for some numbers to hit.
Right now theres a FOMO buy its not that high compare to the previous pump meaning investors know that this is the beginning of bull market, besides we dont see any big corrections right now and the price is still pumping. Its not FOMO if you plan to hold for long term because thats what investors did.
