I would argue that it depends on the future tech development. With the current limitations to Blockchains (mainly speed, costs, centralization of hashpower) one might see a switch to a new technologie f.e the tangle of IOTA. However btc seems to be the equivilant value of all altcoins and therefore I don't believe it will burst like a bubble, but it might stagnate as people move to newer tech sometime in the future. In the end we are only at the beginning of decentralized global network technologies and are only beginning to understand the implementations. Exciting times to live in for sure!
