Years ago people were saying this was all valueless as well, but it has continued to pick up steam. There is truth in that whether not cryptocurrencies can jump the chasm from early adopters to mainstream will depend upon user experience and real value delivery, but we're still at a very early stage for lots of these blockchains. Many will fail, simply because they don't have a sustainable model or the right people behind them, but there are also legit, very powerful models of value delivery being created and those are going to have big futures. To only consider the functionality of something like bitcoin for buying donuts at your local café is maybe pointing out one use case that isn't a great prospect, but it ignores the masses of other important uses that will be fulfilled. It's the wild west right now with lots of bs in the market, but there is gold in them that hills too.
