Few days ago I have went to Ethereum Technical Workshop in Lithuania
In which I had a chance to listen to a developers who already are creating interesting projects on Ethereum.
So we took a deeper look on how Tokens and ICO Smart contracts are being launched on Ethereum Mainnet,
which tools are used and what problems you will face...
For example the main problem right now is that when you submit your code to production, there is no way back, so if you leave a bug, that means that you a screwed...
As you all now what happened with a Parity Wallet (https://www.cryptocoinsnews.com/i-accidentally-killed-it-parity-wallet-bug-locks-150-million-in-ether/)
All in all its great to gain a knowledge in blockchain technologies not only from an investor view but also a developer.
