Why Altcoin has not been priced where Bitcoin Stable has been in the same place for a long time.
Do you think BTC is stable 
so it doesn't disappoint you? I more agree if the price of BTC is unstable so it impacts on altcoin instability. Because in addition to the influence of a country's currency, the effect of BTC prices is very large because most exchange rates in the market also use BTC 
.
