Bitcoin will always be considered as store of value while ETH will be platform for dapps (decentralized applications).
What determines the value of Bitcoin? I mean what justify for the high value? I would like to see it to reach $xxx,xxx in the near future before I go to Heaven.
We would be talking about bitcoin going to 5-6 figures in USD, if it got scaled. Sigh.
What determines the value of Bitcoin is (just like everything else) demand and supply. Bitcoin is limited to 21 million coins only with a mining difficulty that is cut in half every (nearly) 4 years, and its demand is getting slowly bigger every day. Mass adoption (like Japan) is what justifies the high price.
