I believe in bitcoin and blockchain tech, and I think that in the end, there will be a crypto bubble burst, from which several platforms are left standing, bitcoin being one of them. So it's not that BTC is the bubble. Just that this is the only way things can go when there is mass speculation about a new technology that still hasn't reached its full potential. I do think that BTC will emerge (with maybe a couple others) as a giant in this space, but many many others will flop in value.
