Unlikely the price will be stable that long. Bcos the whales will pump the price to get the next bag holders until crypto becomes mainstream.
Yes neither bitcoin nor altcoin price will remain stable for a longer period of time due to the fact that whales will pump and dump the market based on their requirement.
Yeah that's one major factor to consider. There are those who have enough btc to move the market and i don't think these people will allow the price to be stagnant for a very long time.
