The fact is, achievements that have been seen are more desirable than wishful thinking which only ends in nonsense. Bitcoin may not be better in terms of technology compared to many altcoin projects that have emerged lately, but the market capacity and investor confidence that has been formed for quite a long time is difficult to remove. That is why, only projects that have the strength and commitment to continue to develop their products are able to survive.
Of course many project make a lot of promises and most will not deliver, but still I am wondering if Bitcoin can scale and be what people want it to be. If the technology is too old and will not work at big scale, it may stay as a store of value or fade away when better technologies arise.
I see that a lot of people invest and believe in bitcoin, but I just don't see how it will work in long term, for anything else than a store of value.(which may still keep it very expensive)
