Always good to hear someone as clued-up as you affirming thanks Michael!
Crypto can only disappear one way and that is underground. It is just too useful to die.
More and more use cases that promise to deliver better results than was achievable before decentralization was made possible by this technology are being put in place, which means only one thing: growth, as awareness of successes in this realm grows.
And it is most likely that not only the most useful applications will grow - the chances are good that once growth of the star cryptos kick in, there will be another flood of less informed profit seekers investing in whatever they imagine bringing in the boodle.
So, from purely an investment perspective, it may even be wise to bet only a dollar's worth on the weakest ones around that are likely to survive for at least a year or so!
