Ethereum also has to survive the inevitable bugs in the EVM (Ethereum Virtual Machine ) and user written contracts. When those contracts start becoming real with actual value attached and popular enough that it's worth spending time to analyze you're going to see every hacker in the world trying to exploit those contracts. So the real test is can Ethereum survive a confidence loss when the media is running multiple headlines about money disappearing because somebody analyzed a SolC control flow graph using satisfiability and discovered a way to steal millions of dollars.
It's not just exploits... but scams that ultimately kill a platform.
Ethereum reminds me of NXT circa late 2014 when it was worth close to $100 million.
The DAO and the NXT AE are quite similar...
In that they create a vehicle for every Third World scammer to strip the platform of $$$...
So Ethereum is morphing from something serious corporations were building on to becoming a scammer's paradise.
In market terms, the NXT AE was actually more advanced than The DAO...
Because every Asset sold to investors began to trade immediately and became subject to market forces...
While The DAO will give money to unaccountable private groups in exotic jurisdictions.
It doesn't matter if people are anon or not... it's perfectly legal for your business to fail to deliver.
Market forces of the AE exchange was a BIG PLUS, but not enough...
Because 18 months later all the $$$ is in Eastern Europe and NXT is worth only $7 million = dead.
The Ethereum Cult views itself as invincible, but the way The DAO was handled was very scammy and dangerous.
