As a skeptic, people thinking this is a good currency are hilarious. Day trading and making money off them is simple sport.
Are there scalability problems? Yes they are, it's very evident in the transaction fees. But are technical solutions being developed to mitigate this? Yes they are - that's the real work that actually goes on in the background, by the people who actually work, instead of spending their time on internet posting about the price. It's not an easy task, but it is being done.
When people bring up the transaction fees, sometimes it sounds like they think that real Bitcoin developer's don't know that this is a problem. They do, and they work on it! It's just that regular person doesn't want to hear developers, he wants to hear someone that tells them they can make 3x their money over a weekend.
Bcash has increased the blocksize (and forked), which is a perfectly valid solution for such a task, in terms of how a cryptocurrency should be governed: no wars, no lawsuits, if some users don't think a certain decision is valid, they are free to fork off their own chain. No one stopped them, no one tried to shut them down. But the market will ultimately show what is a good solution and what is a bad solution. And you can already see what the market decided in terms of the decision of increasing the block size - by comparing Bitcoin market cap to Bcash market cap.
