Bitcoin and Ethereum are overvalued now, that is why investors pays attention for the new projects that is not so overvalued hoping for the future growth of their token price.
Is that the right strategy? if so, what if the new project doesn't succeed in developing over the allotted time? obviously they will lose right? well, is it wrong if investors always pay attention to Bitcoin and Ethereum for their benefit even though the value is already very high but both are already successful projects with enormous potential.
