Speculating the prices has its pros and cons but I see it as good thing until the crypto market reaches some kind of adoption in the whole world economy because we are not yet up to the level to take into consideration.Currently the speculation is bringing the more people into the market if people don't really care about the prices we may not see such a huge bump in real short time.
people rush into anything that will give more value than normal rate, it is like Dopamine addiction. instant money and richness level varies between people. some can see that level is enough and decide to sell even if they reach the desired level of profit that can make them rich enough, and avoiding to lose this, some can reach that level and get greedy even although that they don't know how they earned this and didn't lose expecting to not lose more.
this depends on each character each case and each market and media speaking about the crypto level.
