yet the biggest problem why btc cant be adopted as a currency is because of its limited supply. meaning price would eventually go up because of scarcity thus making people not wanting to spend.
so PoS has an advantage over there.

I agree with most of what you said except the above. I understand we intuitively assume the above to be true based upon the fear mongering Keynsian economists have instilled in the public when they warn of a deflationary spiral. In practice bitpay has release data reflecting they see spikes in spending when Bitcoin rapidly appreciates (Or goes through disinflationary/adoption bubbles). We have been theorizing that this is due to the wealth effect being more powerful than ones hoarding instinct. When Bitcoin goes up in value people are more generous with tips and spend more because they are wealthier and everything has become cheaper.

Pow for coin distribution and then switch to full POS aka peercoin

Bitcoin may eventually need to modify the algo to provide security if transaction volume doesn't sufficiently ramp up. There are many ways to do this but the great risk for bitcoin is too much vested interest in old mining preventing a transition. This is why Vitalik is considering setting up an inflationary bomb in ethereum to go off for the PoW chain of ether when they decide to switch to some yet to be invented TaPoS variation.
