Bitcoin is many things, and the most important thing is it's a currency outside of the control of governments. Right now that's new enough that it's primary value proposition is anti-inflation (in venezuela) and "digital gold" in much of the world. Is there no legitimate value to letting chinese people move money?

Also, between SegWit, Lightning Network and side chains, the scalability is going to be nearly unlimited in about two years, so the idea that it's not a "viable transaction processing system" seems a bit silly. In fact it works now, globally, without serious problems.

it still is a very viable currency and transaction processing system, I would even argue the best right now for gambling, Bitcoin Cash, a fork of the original Bitcoin, the settlements are even faster, mainstream users can still use normal debit and credit cards, but the settlements will happen behind the scenes with bank-to-bank transfers or bitcoin transfers, its already happening on a small scale
