BTC has got a confident position on the current cryptocurency market thanks to this hype. But I don't think that it is overhyped because its potential is not opened till the end.
Bitcoin is still a fast moving crypto, even after so much ups and down bitcoin is still no.1 in the list. So I don't think it is a hype because of it's potential lot of people showing interest in bitcoin that is the result of which some are saying it as over hype.
