A good reason why bitcoin is so big with cryptocurrency investors is because of the fact that it has good volatility rate that could pump the price up the same way it could dump it down as well. Really volatility is a double-edged sword for investors because most of them use these sudden price surges and drops as a means to earn money with cryptocurrency. The same goes with speculations.
Isn't speculation and volatility a problem for Bitcoin?
If BTC is not speculative and volatile then we don't see that much activity in crypto. Its this volatility that is attracting more and more investors towards this system. If you play your cards sensibility then there are bright chances that you will get good profit from here. If you dont like this volatility then go and invest in banks.
"The higher the risk, the greater the reward" Exactly. Bitcoin being this dynamic is what caused all this craze anyway. So it's not entirely bad for cryptocurrencies to be this way at least while they are still a store-of-value asset. The narrative changes however once they become accepted as bona fide currencies that could be used for everyday menial transactions because the slightest fluctuations could cause problems if volatility is not solved.
