ETH is used by many bad guys. They have created a token with smart contract of ETH too easily and launched scam projects and mobilized a lot of eth from investors. You can see that a lot of eth is sold from ico so the price of eth is always low
Every network that offers censorship resistance will be used by bad guys, too. This is not special to Ethereum. If you want everybody to have access you also have to include the bad guys.
not only Ethereum is used by bad people, many other coins are used to deceive others, because smart people are clever in any way to cheat others.
we must be careful if we want to buy Ethereum,
Ethereum can still grow well and produce, and that depends on how we run and manage it properly.
the choice is not good if you don't have Ethereum, then you can regret it.
There are threats that you just cannot manage. There is no way to account for everything, but what counts is whether Ethereum will do more good than harm and I am convinced that it will be that way.
