Last year in early december I bought eBitcoin token which turned out to be a scam. Luckily for me I sold them before the ePRX snapshot but alot others have made losses. I really believed this token would be a succes but I've realized that alot of these ERC20 tokens have the same things in common. The devs (or better said scammers) create alot of hype and pretend their token to be the real deal while they never intended to create a working product. I've thought about investing in tokens like Credits and Elixir but I'm afraid they are all the same kind of scam.
Do you trust them?
I think this is a classic mix between technology and people using that technology. the technology is innocent of the criminal acts of others. I personally think that the token ERC20 is a great idea.
