Three times in recent past, a crypto coin had a huge spike in the gain category of the market cap. Like 300% or 1200% but that number only lasted for 1 to 2 minutes than it returned to the normal price gain of 7% (as an example). In each case, the 3 coins went to new highs within 2 weeks of the spike. many speculate that when a market chart sight shows an unusual spike that seams to be a computer glitch, that it is really a signal to the wealthy to buy that coin to catch profits.
