It's not deus ex machina, because it's not unexpected. Lightning has a working alpha on Bitcoin, and Ethereum has something similar with Raiden, plus the Plasma paper and early code, a recently-published spec for the first version of sharding with a 100x throughput improvement, various special-purpose off-chain solutions like FunFair's fate channels, TrueBit for verifiable computation off chain, a simple multicore hack, and simulation code for full proof of stake.
I'm not saying there won't be a market correction, since they happen on a regular basis. Just a few months ago Ethereum dropped from $420 to $130.
Yes I am a long term believer in the technology, my gut just says the next correction that comes will be a bloodbath. Accordingly, I'd prefer to wait until that occurs before getting more involved.
If I'm wrong and "lose money" (ie don't get the gains) I'm okay with that too, since I've thought about this a fair amount and I'm confident my position is the most reasonable at this time.
