What was your biggest mistake launching your coin? What do you wish to have known now? .. and how long ago did you launch your altcoin?
I don't get the real purposes of the topic. In my opinion, it is unnecessary somehow.
But, if you have to write something, I think that some of biggest faults to launch a new coin are:
- Starting from original intention to build up scam coins.
- Trying to fraud others with hidden information on instamine, premine (like Bitcoin Private).
- Trying to insert dangerous things in source code of wallets.
