for some reason,altcoin a bit sensitive than bitcoin,even more i guess.on positive ways,we can get a tons of profit when the pump time coming,
I guess you described it the other way around, Bitcoin is more sensitive and reflective to your investment relative to its price unlike the alternatives. Altcoins can hardly double your capital even its price is less than a dollar due to some popularity reasons, even you pray a hundred times that it will pump , it won't.
but the worst,we got REKT when bear come.
i guess the only solution for it just research which coin want you buy,then make a profit target,and consistent for it.
The only solution is to think with a proper basis, always ask yourself if the coin is worth to wait the pump or not. And be too wary of the movements, just like what I have said the popularity of the coin contributes a lot on its price, just look at the top 10 man.
