Take your time, don't cut any corners. Give it a pretty user interface and play the long game, give us the option to use Monero and other altcoins. Basically the internet version of Pablo Escobar just advertised a job vacancy, Lets keep fucking doing this until LE realise that they can't take our freedom and if they think they have a right over what we put in our bodies then that is a perverse abuse of power.
We gave them the option to regulate and tax and they threw it in our faces, cryptocurrencies are the future, banks and governments are losing control and they are fucking terrified.
p.s, invest in cryptocurrency because the only way is up, people are waking up to the fact that keeping your assets in something that depreciates with value isn't a good idea.
Encouraging the top vendors to use Monero would be a step forward.
